# 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.username %>! Not you?
#     <%%= 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]
