+  A ManyArray is a RecordArray that represents the contents of a has-many

+
+  ### Inverses
+
+  Often, the relationships in Ember Data applications will have
+  an inverse. For example, imagine the following models are
+  defined:
+
+      App.Post = DS.Model.extend({
+        comments: DS.hasMany('App.Comment')
+      });
+
+      App.Comment = DS.Model.extend({
+        post: DS.belongsTo('App.Post')
+      });
+
+  If you created a new instance of `App.Post` and added
+  a `App.Comment` record to its `comments` has-many
+  relationship, you would expect the comment's `post`
+  property to be set to the post that contained
+  the has-many.
+
+  We call the record to which a relationship belongs the
+  relationship's _owner_.

+/**
+  A transaction allows you to collect multiple records into a unit of work
+  that can be committed or rolled back as a group.
+
+  For example, if a record has local modifications that have not yet
+  been saved, calling `commit()` on its transaction will cause those
+  modifications to be sent to the adapter to be saved. Calling
+  `rollback()` on its transaction would cause all of the modifications to
+  be discarded and the record to return to the last known state before
+  changes were made.
+
+  If a newly created record's transaction is rolled back, it will
+  immediately transition to the deleted state.
+
+  If you do not explicitly create a transaction, a record is assigned to
+  an implicit transaction called the default transaction. In these cases,
+  you can treat your application's instance of `DS.Store` as a transaction
+  and call the `commit()` and `rollback()` methods on the store itself.
+
+  Once a record has been successfully committed or rolled back, it will
+  be moved back to the implicit transaction. Because it will now be in
+  a clean state, it can be moved to a new transaction if you wish.
+
+  ### Creating a Transaction
+
+  To create a new transaction, call the `transaction()` method of your
+  application's `DS.Store` instance:
+
+      var transaction = App.store.transaction();
+
+  This will return a new instance of `DS.Transaction` with no records
+  yet assigned to it.
+
+  ### Adding Existing Records
+
+  Add records to a transaction using the `add()` method:
+
+      record = App.store.find(App.Person, 1);
+      transaction.add(record);
+
+  Note that only records whose `isDirty` flag is `false` may be added
+  to a transaction. Once modifications to a record have been made
+  (its `isDirty` flag is `true`), it is not longer able to be added to
+  a transaction.
+
+  ### Creating New Records
+
+  Because newly created records are dirty from the time they are created,
+  and because dirty records can not be added to a transaction, you must
+  use the `createRecord()` method to assign new records to a transaction.
+
+  For example, instead of this:
+
+    var transaction = store.transaction();
+    var person = App.Person.createRecord({ name: "Steve" });
+
+    // won't work because person is dirty
+    transaction.add(person);
+
+  Call `createRecord()` on the transaction directly:
+
+    var transaction = store.transaction();
+    transaction.createRecord(App.Person, { name: "Steve" });
+
+  ### Asynchronous Commits
+
+  Typically, all of the records in a transaction will be committed
+  together. However, new records that have a dependency on other new
+  records need to wait for their parent record to be saved and assigned an
+  ID. In that case, the child record will continue to live in the
+  transaction until its parent is saved, at which time the transaction will
+  attempt to commit again.
+
+  For this reason, you should not re-use transactions once you have committed
+  them. Always make a new transaction and move the desired records to it before
+  calling commit.

+
+  The Mappable mixin is designed for classes that would like to
+  behave as a map for configuration purposes.
+
+  For example, the DS.Adapter class can behave like a map, with
+  more semantic API, via the `map` API:
+
+    DS.Adapter.map('App.Person', { firstName: { keyName: 'FIRST' } });
+
+  Class configuration via a map-like API has a few common requirements
+  that differentiate it from the standard Ember.Map implementation.
+
+  First, values often are provided as strings that should be normalized
+  into classes the first time the configuration options are used.
+
+  Second, the values configured on parent classes should also be taken
+  into account.
+
+  Finally, setting the value of a key sometimes should merge with the
+  previous value, rather than replacing it.
+
+  This mixin provides a instance method, `createInstanceMapFor`, that
+  will reify all of the configuration options set on an instance's
+  constructor and provide it for the instance to use.
+
+  Classes can implement certain hooks that allow them to customize
+  the requirements listed above:
+
+  * `resolveMapConflict` - called when a value is set for an existing
+    value
+  * `transformMapKey` - allows a key name (for example, a global path
+    to a class) to be normalized
+  * `transformMapValue` - allows a value (for example, a class that
+    should be instantiated) to be normalized
+
+  Classes that implement this mixin should also implement a class
+  method built using the `generateMapFunctionFor` method:
+
+    DS.Adapter.reopenClass({
+      map: DS.Mappable.generateMapFunctionFor('attributes', function(key, newValue, map) {
+        var existingValue = map.get(key);
+
+        for (var prop in newValue) {
+          if (!newValue.hasOwnProperty(prop)) { continue; }
+          existingValue[prop] = newValue[prop];
+        }
+      })
+    });
+
+   The function passed to `generateMapFunctionFor` is invoked every time a
+   new value is added to the map.

+    based upon the adapter's semantics.
+
+    There are three basic scenarios by which an adapter can
+    save a relationship.
+
+    ### Foreign Key
+
+    An adapter can save all relationship changes by updating
+    a foreign key on the child record. If it does this, it
+    should acknowledge the changes when the child record is
+    saved.
+
+        record.eachRelationship(function(name, meta) {

+        });
+
+        store.didSaveRecord(record, data);
+
+    ### Embedded in Parent
+
+    An adapter can save one-to-many relationships by embedding
+    IDs (or records) in the parent object. In this case, the
+    relationship is not considered acknowledged until both the
+    old parent and new parent have acknowledged the change.
+
+    In this case, the adapter should keep track of the old
+    parent and new parent, and acknowledge the relationship
+    change once both have acknowledged. If one of the two
+    sides does not exist (e.g. the new parent does not exist
+    because of nulling out the belongs-to relationship),
+    the adapter should acknowledge the relationship once
+    the other side has acknowledged.
+
+    ### Separate Entity
+
+    An adapter can save relationships as separate entities
+    on the server. In this case, they should acknowledge
+    the relationship as saved once the server has
+    acknowledged the entity.

+/**
+  This file encapsulates the various states that a record can transition
+  through during its lifecycle.
+
+  ### State Manager
+
+  A record's state manager explicitly tracks what state a record is in
+  at any given time. For instance, if a record is newly created and has
+  not yet been sent to the adapter to be saved, it would be in the
+  `created.uncommitted` state.  If a record has had local modifications
+  made to it that are in the process of being saved, the record would be
+  in the `updated.inFlight` state. (These state paths will be explained
+  in more detail below.)
+
+  Events are sent by the record or its store to the record's state manager.
+  How the state manager reacts to these events is dependent on which state
+  it is in. In some states, certain events will be invalid and will cause
+  an exception to be raised.
+
+  States are hierarchical. For example, a record can be in the
+  `deleted.start` state, then transition into the `deleted.inFlight` state.
+  If a child state does not implement an event handler, the state manager
+  will attempt to invoke the event on all parent states until the root state is
+  reached. The state hierarchy of a record is described in terms of a path
+  string. You can determine a record's current state by getting its manager's
+  current state path:
+
+      record.get('stateManager.currentPath');
+      //=> "created.uncommitted"
+
+  The `DS.Model` states are themselves stateless. What we mean is that,
+  though each instance of a record also has a unique instance of a
+  `DS.StateManager`, the hierarchical states that each of *those* points
+  to is a shared data structure. For performance reasons, instead of each
+  record getting its own copy of the hierarchy of states, each state
+  manager points to this global, immutable shared instance. How does a
+  state know which record it should be acting on?  We pass a reference to
+  the current state manager as the first parameter to every method invoked
+  on a state.
+
+  The state manager passed as the first parameter is where you should stash
+  state about the record if needed; you should never store data on the state
+  object itself. If you need access to the record being acted on, you can
+  retrieve the state manager's `record` property. For example, if you had
+  an event handler `myEvent`:
+
+      myEvent: function(manager) {
+        var record = manager.get('record');
+        record.doSomething();
+      }
+
+  For more information about state managers in general, see the Ember.js
+  documentation on `Ember.StateManager`.
+
+  ### Events, Flags, and Transitions
+
+  A state may implement zero or more events, flags, or transitions.
+
+  #### Events
+
+  Events are named functions that are invoked when sent to a record. The
+  state manager will first look for a method with the given name on the
+  current state. If no method is found, it will search the current state's
+  parent, and then its grandparent, and so on until reaching the top of
+  the hierarchy. If the root is reached without an event handler being found,
+  an exception will be raised. This can be very helpful when debugging new
+  features.
+
+  Here's an example implementation of a state with a `myEvent` event handler:
+
+      aState: DS.State.create({
+        myEvent: function(manager, param) {
+          console.log("Received myEvent with "+param);
+        }
+      })
+
+  To trigger this event:
+
+      record.send('myEvent', 'foo');
+      //=> "Received myEvent with foo"
+
+  Note that an optional parameter can be sent to a record's `send()` method,
+  which will be passed as the second parameter to the event handler.
+
+  Events should transition to a different state if appropriate. This can be
+  done by calling the state manager's `transitionTo()` method with a path to the
+  desired state. The state manager will attempt to resolve the state path
+  relative to the current state. If no state is found at that path, it will
+  attempt to resolve it relative to the current state's parent, and then its
+  parent, and so on until the root is reached. For example, imagine a hierarchy
+  like this:
+
+      * created
+        * start <-- currentState
+        * inFlight
+      * updated
+        * inFlight
+
+  If we are currently in the `start` state, calling
+  `transitionTo('inFlight')` would transition to the `created.inFlight` state,
+  while calling `transitionTo('updated.inFlight')` would transition to
+  the `updated.inFlight` state.
+
+  Remember that *only events* should ever cause a state transition. You should
+  never call `transitionTo()` from outside a state's event handler. If you are
+  tempted to do so, create a new event and send that to the state manager.
+
+  #### Flags
+
+  Flags are Boolean values that can be used to introspect a record's current
+  state in a more user-friendly way than examining its state path. For example,
+  instead of doing this:
+
+      var statePath = record.get('stateManager.currentPath');
+      if (statePath === 'created.inFlight') {
+        doSomething();
+      }
+
+  You can say:
+
+      if (record.get('isNew') && record.get('isSaving')) {
+        doSomething();
+      }
+
+  If your state does not set a value for a given flag, the value will
+  be inherited from its parent (or the first place in the state hierarchy
+  where it is defined).
+
+  The current set of flags are defined below. If you want to add a new flag,
+  in addition to the area below, you will also need to declare it in the
+  `DS.Model` class.
+
+  #### Transitions
+
+  Transitions are like event handlers but are called automatically upon
+  entering or exiting a state. To implement a transition, just call a method
+  either `enter` or `exit`:
+
+      myState: DS.State.create({
+        // Gets called automatically when entering
+        // this state.
+        enter: function(manager) {
+          console.log("Entered myState");
+        }
+      })
+
+   Note that enter and exit events are called once per transition. If the
+   current state changes, but changes to another child state of the parent,
+   the transition event on the parent will not be triggered.

+
+// Implementation notes:
+//
+// Each state has a boolean value for all of the following flags:
+//
+// * isLoaded: The record has a populated `data` property. When a
+//   record is loaded via `store.find`, `isLoaded` is false
+//   until the adapter sets it. When a record is created locally,
+//   its `isLoaded` property is always true.
+// * isDirty: The record has local changes that have not yet been
+//   saved by the adapter. This includes records that have been
+//   created (but not yet saved) or deleted.
+// * isSaving: The record's transaction has been committed, but
+//   the adapter has not yet acknowledged that the changes have
+//   been persisted to the backend.
+// * isDeleted: The record was marked for deletion. When `isDeleted`
+//   is true and `isDirty` is true, the record is deleted locally
+//   but the deletion was not yet persisted. When `isSaving` is
+//   true, the change is in-flight. When both `isDirty` and
+//   `isSaving` are false, the change has persisted.
+// * isError: The adapter reported that it was unable to save
+//   local changes to the backend. This may also result in the
+//   record having its `isValid` property become false if the
+//   adapter reported that server-side validations failed.
+// * isNew: The record was created on the client and the adapter
+//   did not yet report that it was successfully saved.
+// * isValid: No client-side validations have failed and the
+//   adapter did not report any server-side validation failures.
+
+// The dirty state is a abstract state whose functionality is
+// shared between the `created` and `updated` states.
+//
+// The deleted state shares the `isDirty` flag with the
+// subclasses of `DirtyState`, but with a very different
+// implementation.
+//
+// Dirty states have three child states:
+//
+// `uncommitted`: the store has not yet handed off the record
+//   to be saved.

+/**
+  A serializer is responsible for serializing and deserializing a group of
+  records.
+
+  `DS.Serializer` is an abstract base class designed to help you build a
+  serializer that can read to and write from any serialized form.  While most
+  applications will use `DS.JSONSerializer`, which reads and writes JSON, the
+  serializer architecture allows your adapter to transmit things like XML,
+  strings, or custom binary data.
+
+  Typically, your application's `DS.Adapter` is responsible for both creating a
+  serializer as well as calling the appropriate methods when it needs to
+  materialize data or serialize a record.
+
+  The serializer API is designed as a series of layered hooks that you can
+  override to customize any of the individual steps of serialization and
+  deserialization.
+
+  The hooks are organized by the three responsibilities of the serializer:
+
+  1. Determining naming conventions
+  2. Serializing records into a serialized form
+  3. Deserializing records from a serialized form
+
+  Because Ember Data lazily materializes records, the deserialization
+  step, and therefore the hooks you implement, are split into two phases:
+
+  1. Extraction, where the serialized forms for multiple records are
+     extracted from a single payload. The IDs of each record are also
+     extracted for indexing.
+  2. Materialization, where a newly-created record has its attributes
+     and relationships initialized based on the serialized form loaded
+     by the adapter.
+
+  Additionally, a serializer can convert values from their JavaScript
+  versions into their serialized versions via a declarative API.
+
+  ## Naming Conventions
+
+  One of the most common uses of the serializer is to map attribute names
+  from the serialized form to your `DS.Model`. For example, in your model,
+  you may have an attribute called `firstName`:
+
+  ```javascript
+  App.Person = DS.Model.extend({
+    firstName: DS.attr('string')
+  });
+  ```
+
+  However, because the web API your adapter is communicating with is
+  legacy, it calls this attribute `FIRST_NAME`.
+
+  You can determine the attribute name used in the serialized form
+  by implementing `keyForAttributeName`:
+
+  ```javascript
+    keyForAttributeName: function(type, name) {
+      return name.underscore.toUpperCase();
+    }
+  ```
+
+  If your attribute names are not predictable, you can re-map them
+  one-by-one using the `map` API:
+
+  ```javascript
+  App.Person.map('App.Person', {
+    firstName: { key: '*API_USER_FIRST_NAME*' }
+  });
+  ```
+
+  ## Serialization
+
+  During the serialization process, a record or records are converted
+  from Ember.js objects into their serialized form.
+
+  These methods are designed in layers, like a delicious 7-layer
+  cake (but with fewer layers).
+
+  The main entry point for serialization is the `serialize`
+  method, which takes the record and options.
+
+  The `serialize` method is responsible for:
+
+  * turning the record's attributes (`DS.attr`) into
+    attributes on the JSON object.
+  * optionally adding the record's ID onto the hash
+  * adding relationships (`DS.hasMany` and `DS.belongsTo`)
+    to the JSON object.
+
+  Depending on the backend, the serializer can choose
+  whether to include the `hasMany` or `belongsTo`
+  relationships on the JSON hash.
+
+  For very custom serialization, you can implement your
+  own `serialize` method. In general, however, you will want
+  to override the hooks described below.
+
+  ### Adding the ID
+
+  The default `serialize` will optionally call your serializer's
+  `addId` method with the JSON hash it is creating, the
+  record's type, and the record's ID. The `serialize` method
+  will not call `addId` if the record's ID is undefined.
+
+  Your adapter must specifically request ID inclusion by
+  passing `{ includeId: true }` as an option to `serialize`.
+
+  NOTE: You may not want to include the ID when updating an
+  existing record, because your server will likely disallow
+  changing an ID after it is created, and the PUT request
+  itself will include the record's identification.
+
+  By default, `addId` will:
+
+  1. Get the primary key name for the record by calling
+     the serializer's `primaryKey` with the record's type.
+     Unless you override the `primaryKey` method, this
+     will be `'id'`.
+  2. Assign the record's ID to the primary key in the
+     JSON hash being built.
+
+  If your backend expects a JSON object with the primary
+  key at the root, you can just override the `primaryKey`
+  method on your serializer subclass.
+
+  Otherwise, you can override the `addId` method for
+  more specialized handling.
+
+  ### Adding Attributes
+
+  By default, the serializer's `serialize` method will call
+  `addAttributes` with the JSON object it is creating
+  and the record to serialize.
+
+  The `addAttributes` method will then call `addAttribute`
+  in turn, with the JSON object, the record to serialize,
+  the attribute's name and its type.
+
+  Finally, the `addAttribute` method will serialize the
+  attribute:
+
+  1. It will call `keyForAttributeName` to determine
+     the key to use in the JSON hash.
+  2. It will get the value from the record.
+  3. It will call `serializeValue` with the attribute's
+     value and attribute type to convert it into a
+     JSON-compatible value. For example, it will convert a
+     Date into a String.
+
+  If your backend expects a JSON object with attributes as
+  keys at the root, you can just override the `serializeValue`
+  and `keyForAttributeName` methods in your serializer
+  subclass and let the base class do the heavy lifting.
+
+  If you need something more specialized, you can probably
+  override `addAttribute` and let the default `addAttributes`
+  handle the nitty gritty.
+
+  ### Adding Relationships
+
+  By default, `serialize` will call your serializer's
+  `addRelationships` method with the JSON object that is
+  being built and the record being serialized. The default
+  implementation of this method is to loop over all of the
+  relationships defined on your record type and:
+
+  * If the relationship is a `DS.hasMany` relationship,
+    call `addHasMany` with the JSON object, the record
+    and a description of the relationship.
+  * If the relationship is a `DS.belongsTo` relationship,
+    call `addBelongsTo` with the JSON object, the record
+    and a description of the relationship.
+
+  The relationship description has the following keys:
+
+  * `type`: the class of the associated information (the
+    first parameter to `DS.hasMany` or `DS.belongsTo`)
+  * `kind`: either `hasMany` or `belongsTo`
+
+  The relationship description may get additional
+  information in the future if more capabilities or
+  relationship types are added. However, it will
+  remain backwards-compatible, so the mere existence
+  of new features should not break existing adapters.

+/**
+  An adapter is an object that receives requests from a store and
+  translates them into the appropriate action to take against your
+  persistence layer. The persistence layer is usually an HTTP API, but may
+  be anything, such as the browser's local storage.
+
+  ### Creating an Adapter
+
+  First, create a new subclass of `DS.Adapter`:
+
+      App.MyAdapter = DS.Adapter.extend({
+        // ...your code here
+      });
+
+  To tell your store which adapter to use, set its `adapter` property:
+
+      App.store = DS.Store.create({
+        revision: 3,
+        adapter: App.MyAdapter.create()
+      });
+
+  `DS.Adapter` is an abstract base class that you should override in your
+  application to customize it for your backend. The minimum set of methods
+  that you should implement is:
+
+    * `find()`
+    * `createRecord()`
+    * `updateRecord()`
+    * `deleteRecord()`
+
+   To improve the network performance of your application, you can optimize
+   your adapter by overriding these lower-level methods:
+
+    * `findMany()`
+    * `createRecords()`
+    * `updateRecords()`
+    * `deleteRecords()`
+    * `commit()`
+*/
+
+var get = Ember.get, set = Ember.set, merge = Ember.merge;
+
+DS.Adapter = Ember.Object.extend(DS._Mappable, {
+
+  init: function() {
+    var serializer = get(this, 'serializer');
+
+    if (Ember.Object.detect(serializer)) {
+      serializer = serializer.create();
+      set(this, 'serializer', serializer);
+    }
+

+    Loads a payload for a record into the store.
+
+    This method asks the serializer to break the payload into
+    constituent parts, and then loads them into the store. For example,
+    if you have a payload that contains embedded records, they will be
+    extracted by the serializer and loaded into the store.
+
+    For example:
+
+    ```javascript
+      adapter.load(store, App.Person, {
+        id: 123,
+        firstName: "Yehuda",
+        lastName: "Katz",

+          id: 345,
+          title: "Tricycle Mechanic"
+        }]    
+      });
+    ```
+
+    This will load the payload for the `App.Person` with ID `123` and
+    the embedded `App.Occupation` with ID `345`.

+/**
+  The REST adapter allows your store to communicate with an HTTP server by
+  transmitting JSON via XHR. Most Ember.js apps that consume a JSON API
+  should use the REST adapter.
+
+  This adapter is designed around the idea that the JSON exchanged with
+  the server should be conventional.
+
+  ## JSON Structure
+
+  The REST adapter expects the JSON returned from your server to follow
+  these conventions.
+
+  ### Object Root
+
+  The JSON payload should be an object that contains the record inside a
+  root property. For example, in response to a `GET` request for
+  `/posts/1`, the JSON should look like this:
+
+  ```js
+  {
+    "post": {
+      title: "I'm Running to Reform the W3C's Tag",
+      author: "Yehuda Katz"
+    }
+  }
+  ```
+
+  ### Conventional Names
+
+  Attribute names in your JSON payload should be the underscored versions of
+  the attributes in your Ember.js models.
+
+  For example, if you have a `Person` model:
+
+  ```js
+  App.Person = DS.Model.extend({
+    firstName: DS.attr('string'),
+    lastName: DS.attr('string'),
+    occupation: DS.attr('string')
+  });
+  ```
+
+  The JSON returned should look like this:
+
+  ```js
+  {
+    "person": {
+      "first_name": "Barack",
+      "last_name": "Obama",
+      "occupation": "President"
+    }
+  }
+  ```
