+  Schedules an item to run from within a separate run loop, after 
+  control has been returned to the system. This is equivalent to calling 
+  `Ember.run.later` with a wait time of 1ms.
 
   ```javascript
   Ember.run.next(myContext, function(){
-    // code to be executed in the next RunLoop, which will be scheduled after the current one
+    // code to be executed in the next run loop, which will be scheduled after the current one
+  });
+  ```
+
+  Multiple operations scheduled with `Ember.run.next` will coalesce
+  into the same later run loop, along with any other operations
+  scheduled by `Ember.run.later` that expire right around the same
+  time that `Ember.run.next` operations will fire. 
+
+  Note that there are often alternatives to using `Ember.run.next`.
+  For instance, if you'd like to schedule an operation to happen
+  after all DOM element operations have completed within the current
+  run loop, you can make use of the `afterRender` run loop queue (added
+  by the `ember-views` package, along with the preceding `render` queue
+  where all the DOM element operations happen). Example:
+
+  ```javascript
+  App.MyCollectionView = Ember.CollectionView.extend({
+    didInsertElement: function() {
+      Ember.run.scheduleOnce('afterRender', this, 'processChildElements');
+    },
+    processChildElements: function() {
+      // ... do something with collectionView's child view
+      // elements after they've finished rendering, which
+      // can't be done within the CollectionView's
+      // `didInsertElement` hook because that gets run
+      // before the child elements have been added to the DOM.
+    }
   });
   ```
 
+  One benefit of the above approach compared to using `Ember.run.next` is
+  that you will be able to perform DOM/CSS operations before unprocessed
+  elements are rendered to the screen, which may prevent flickering or 
+  other artifacts caused by delaying processing until after rendering.
+
+  The other major benefit to the above approach is that `Ember.run.next` 
+  introduces an element of non-determinism, which can make things much 
+  harder to test, due to its reliance on `setTimeout`; it's much harder 
+  to guarantee the order of scheduled operations when they are scheduled 
+  outside of the current run loop, i.e. with `Ember.run.next`.

-  also iterate through a set just like an array, even accessing objects by

-  All Sets are observable via the Enumerable Observer API - which works
-  on any enumerable object including both Sets and Arrays.
+})();
 
-  ## Creating a Set
 
-  You can create a set like you would most objects using
-  `new Ember.Set()`. Most new sets you create will be empty, but you can
-  also initialize the set with some content by passing an array or other
-  enumerable of objects to the constructor.
 
-  Finally, you can pass in an existing set and the set will be copied. You
-  can also create a copy of a set by calling `Ember.Set#copy()`.
+(function() {
+/**
+@module ember
+@submodule ember-runtime
+*/
 
-  ```javascript
-  // creates a new empty set
-  var foundNames = new Ember.Set();
+var get = Ember.get, indexOf = Ember.ArrayPolyfills.indexOf;
 
-  // creates a set with four names in it.
-  var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P
+/**
+  A Namespace is an object usually used to contain other objects or methods
+  such as an application or framework. Create a namespace anytime you want
+  to define one of these new containers.
 
-  // creates a copy of the names set.
-  var namesCopy = new Ember.Set(names);
+  # Example Usage
 
-  // same as above.
-  var anotherNamesCopy = names.copy();
+  ```javascript
+  MyFramework = Ember.Namespace.create({
+    VERSION: '1.0.0'
+  });
   ```
 
-  ## Adding/Removing Objects
+  @class Namespace
+  @namespace Ember
+  @extends Ember.Object
+*/
+var Namespace = Ember.Namespace = Ember.Object.extend({
+  isNamespace: true,
 
-  You generally add or remove objects from a set using `add()` or
-  `remove()`. You can add any type of object including primitives such as
-  numbers, strings, and booleans.
+  init: function() {
+    Ember.Namespace.NAMESPACES.push(this);
+    Ember.Namespace.PROCESSED = false;
+  },
 
-  Unlike arrays, objects can only exist one time in a set. If you call `add()`
-  on a set with the same object multiple times, the object will only be added
-  once. Likewise, calling `remove()` with the same object multiple times will
-  remove the object the first time and have no effect on future calls until
-  you add the object to the set again.
+  toString: function() {
+    var name = get(this, 'name');
+    if (name) { return name; }
 
-  NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do
-  so will be ignored.
+    findNamespaces();
+    return this[Ember.GUID_KEY+'_name'];
+  },
 
-  In addition to add/remove you can also call `push()`/`pop()`. Push behaves
-  just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary
-  object, remove it and return it. This is a good way to use a set as a job
-  queue when you don't care which order the jobs are executed in.
+  nameClasses: function() {
+    processNamespace([this.toString()], this, {});
+  },
 
-  ## Testing for an Object
+  destroy: function() {
+    var namespaces = Ember.Namespace.NAMESPACES;
+    Ember.lookup[this.toString()] = undefined;
+    namespaces.splice(indexOf.call(namespaces, this), 1);
+    this._super();
+  }
+});
 
-  To test for an object's presence in a set you simply call
-  `Ember.Set#contains()`.
+Namespace.reopenClass({
+  NAMESPACES: [Ember],
+  NAMESPACES_BY_ID: {},
+  PROCESSED: false,
+  processAll: processAllNamespaces,
+  byName: function(name) {
+    if (!Ember.BOOTED) {
+      processAllNamespaces();
+    }
 
-  ## Observing changes
+    return NAMESPACES_BY_ID[name];
+  }
+});
 
-  When using `Ember.Set`, you can observe the `"[]"` property to be
-  alerted whenever the content changes. You can also add an enumerable
-  observer to the set to be notified of specific objects that are added and
-  removed from the set. See `Ember.Enumerable` for more information on
-  enumerables.
+var NAMESPACES_BY_ID = Namespace.NAMESPACES_BY_ID;
 
-  This is often unhelpful. If you are filtering sets of objects, for instance,
-  it is very inefficient to re-filter all of the items each time the set
-  changes. It would be better if you could just adjust the filtered set based
-  on what was changed on the original set. The same issue applies to merging
-  sets, as well.

-  `Ember.Set` primary implements other mixin APIs. For a complete reference
-  on the methods you will use with `Ember.Set`, please consult these mixins.
-  The most useful ones will be `Ember.Enumerable` and
-  `Ember.MutableEnumerable` which implement most of the common iterator

-  Note that you can also use the `Ember.Copyable` and `Ember.Freezable`
-  APIs on `Ember.Set` as well. Once a set is frozen it can no longer be
-  modified. The benefit of this is that when you call `frozenCopy()` on it,
-  Ember will avoid making copies of the set. This allows you to write
-  code that can know with certainty when the underlying set data will or
-  will not be modified.

-
-  # Example Usage

-    store: Ember.Store.create().from(Ember.fixtures)
-  });
-
-  MyApp.ready = function() {

+function addObserverForContentKey(content, keyName, proxy, idx, loc) {
+  var objects = proxy._objects, guid;
+  if (!objects) objects = proxy._objects = {};
 
-  A simple example of usage:
+  while(--loc>=idx) {
+    var item = content.objectAt(loc);
+    if (item) {
+      Ember.addBeforeObserver(item, keyName, proxy, 'contentKeyWillChange');

-  ```javascript

-  var ap = Ember.ArrayProxy.create({ content: Ember.A(pets) });
+      // keep track of the index each item was found at so we can map

-  ```

-  This class can also be useful as a layer to transform the contents of

-  `objectAtContent`:

+  You generally add or remove objects from a set using `add()` or
+  `remove()`. You can add any type of object including primitives such as
+  numbers, strings, and booleans.

-}
+  Unlike arrays, objects can only exist one time in a set. If you call `add()`
+  on a set with the same object multiple times, the object will only be added
+  once. Likewise, calling `remove()` with the same object multiple times will
+  remove the object the first time and have no effect on future calls until
+  you add the object to the set again.
 
-/**
-  This is the object instance returned when you get the `@each` property on an
-  array. It uses the unknownProperty handler to automatically create
-  EachArray instances for property names.
+  NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do
+  so will be ignored.
 
-  @private
-  @class EachProxy
+  In addition to add/remove you can also call `push()`/`pop()`. Push behaves
+  just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary
+  object, remove it and return it. This is a good way to use a set as a job
+  queue when you don't care which order the jobs are executed in.
+
+  ## Testing for an Object
+
+  To test for an object's presence in a set you simply call
+  `Ember.Set#contains()`.
+
+  ## Observing changes
+
+  When using `Ember.Set`, you can observe the `"[]"` property to be
+  alerted whenever the content changes. You can also add an enumerable
+  observer to the set to be notified of specific objects that are added and
+  removed from the set. See `Ember.Enumerable` for more information on
+  enumerables.
+
+  This is often unhelpful. If you are filtering sets of objects, for instance,
+  it is very inefficient to re-filter all of the items each time the set
+  changes. It would be better if you could just adjust the filtered set based
+  on what was changed on the original set. The same issue applies to merging
+  sets, as well.
+
+  ## Other Methods
+
+  `Ember.Set` primary implements other mixin APIs. For a complete reference
+  on the methods you will use with `Ember.Set`, please consult these mixins.
+  The most useful ones will be `Ember.Enumerable` and
+  `Ember.MutableEnumerable` which implement most of the common iterator
+  methods you are used to on Array.
+
+  Note that you can also use the `Ember.Copyable` and `Ember.Freezable`
+  APIs on `Ember.Set` as well. Once a set is frozen it can no longer be
+  modified. The benefit of this is that when you call `frozenCopy()` on it,
+  Ember will avoid making copies of the set. This allows you to write
+  code that can know with certainty when the underlying set data will or
+  will not be modified.

-    The `outlet` helper allows you to specify that the current

+    The `outlet` helper is a placeholder that the router will fill in with
+    the appropriate template based on the current state of the application.
 
     ``` handlebars
     {{outlet}}
     ```
 
-    By default, when the the current controller's `view` property changes, the
-    outlet will replace its current view with the new view. You can set the
-    `view` property directly, but it's normally best to use `connectOutlet`.
+    By default, a template based on Ember's naming conventions will be rendered
+    into the `outlet` (e.g. `App.PostsRoute` will render the `posts` template).
+
+    You can render a different template by using the `render()` method in the
+    route's `renderTemplate` hook. The following will render the `favoritePost`
+    template into the `outlet`.
 
     ``` javascript
-    # Instantiate App.PostsView and assign to `view`, so as to render into outlet.
-    controller.connectOutlet('posts');
+    App.PostsRoute = Ember.Route.extend({
+      renderTemplate: function() {
+        this.render('favoritePost');
+      }
+    });
     ```
 
-    You can also specify a particular name other than `view`:
+    You can create custom named outlets for more control.
 
     ``` handlebars
-    {{outlet masterView}}
-    {{outlet detailView}}
+    {{outlet favoritePost}}
+    {{outlet posts}}
     ```
 
-    Then, you can control several outlets from a single controller.
+    Then you can define what template is rendered into each outlet in your
+    route.
+
 
     ``` javascript
-    # Instantiate App.PostsView and assign to controller.masterView.
-    controller.connectOutlet('masterView', 'posts');

+  The container calls this object's `resolve` method with the
+  `fullName` argument.
+
+  It first parses the fullName into an object using `parseName`.
+
+  Then it checks for the presence of a type-specific instance
+  method of the form `resolve[Type]` and calls it if it exists.
+  For example if it was resolving 'template:post', it would call
+  the `resolveTemplate` method.
+
+  Its last resort is to call the `resolveOther` method.
+
+  The methods of this object are designed to be easy to override
+  in a subclass. For example, you could enhance how a template
+  is resolved like so:
+
+  ```javascript
+  App = Ember.Application.create({
+    resolver: Ember.DefaultResolver.extend({
+      resolveTemplate: function(parsedName) {
+        var resolvedTemplate = this._super(parsedName);
+        if (resolvedTemplate) { return resolvedTemplate; }
+        return Ember.TEMPLATES['not_found'];
+      }
+    })
+  });
+  ```
+
+  Some examples of how names are resolved:
+
+  ```
+  'template:post' //=> Ember.TEMPLATES['post']
+  'template:posts/byline' //=> Ember.TEMPLATES['posts/byline']
+  'template:posts.byline' //=> Ember.TEMPLATES['posts/byline']
+  'template:blogPost' //=> Ember.TEMPLATES['blogPost']
+                      //   OR
+                      //   Ember.TEMPLATES['blog_post']
+  'controller:post' //=> App.PostController
+  'controller:posts.index' //=> App.PostsIndexController
+  'controller:blog/post' //=> Blog.PostController
+  'controller:basic' //=> Ember.Controller
+  'route:post' //=> App.PostRoute
+  'route:posts.index' //=> App.PostsIndexRoute
+  'route:blog/post' //=> Blog.PostRoute
+  'route:basic' //=> Ember.Route
+  'view:post' //=> App.PostView
+  'view:posts.index' //=> App.PostsIndexView
+  'view:blog/post' //=> Blog.PostView
+  'view:basic' //=> Ember.View
+  'foo:post' //=> App.PostFoo
+  ```
