Added Foundation Gem
Got cancan authorization working for individuals entity. 1. Modified ability.rb file to take care of the case where user is nil. 2. Had to write 'authorize! action, entity' for each controller action in the individuals controller. There must be a simpler way besides load_and_authorize_resource since this kept giving an AttributesError.
