OpensocialContainer
===================
This plugin is designed to pull together all of the neccessary components involved in turning your application in to an 
OpenSocial container capable of hosting OpenSocial applications.  Beyond the raw functionality this plugin is being 
built to make the practice of presenting a secure and stable container simple and straightforward by adopting best 
practices as they are defined.

Example
=======
In the config/routes.rb file:
ActionController::Routing::Routes.draw do |map|
  ...
  map.opensocial_container "contain.localhost" # this will be turned in to <instance_id>.contain.localhost
end
To add the "feeds" resources:
ruby script/generator opensocial
If you support the OpenSocial REST API already, then use this instead to avoid the app/ pollution:
ruby script/generator opensocial_assets
And finally to embed the container in a ERb template use the helper:
<%= opensocial_container('https://www.last.fm/opensocial/myfavouritemusic.xml', :owner => @user, :viewer => current_user, 
:instance_id => instance.id) %>
In the config/environment.rb you need to add
OpenSocialContainer::Configuration.person_class = 'User'
OpenSocialContainer::Configuration.secret = 'a secret password'
to get the support for people to be your "User" class.  The user needs to have:
def self.opensocial_id_column_name; 'id'; end
and should define a title:
def title; self.display_name; end
Caveats
=======
This plugin is in very early development and should be used with that in mind.  While hopefully not too buggy, it may be 
feature lacking in a number of respects.
