# This module is included in your application controller which makes
# several methods available to all controllers and views. Here's a
# common example you might add to your application layout file.
#
# <%% if logged_in? %>
# Welcome <%%= current_<%= user_singular_name %>.username %>.
# <%%= link_to "Edit profile", edit_current_<%= user_singular_name %>_path %> or
# <%%= link_to "Log out", logout_path %>
# <%% else %>
# <%%= link_to "Sign up", signup_path %> or
# <%%= link_to "log in", login_path %>.
# <%% end %>
#
# You can also restrict unregistered users from accessing a controller using
# a before filter. For example.
#
# before_filter :login_required, :except => [:index, :show]
