# Returns source file name of required model. 
# 
# Used wherever end user wants to extend basic DrgCms model. Model source definition 
# file is tricky to require since it is included in DrgCms gem and thus a moving 
# target. Whenever gem version changes file location changes with it. This way 
# end user doesn't have to care about actual source file location.
#   
# Parameters:
# [ model_name ] String. Must be passed in lower case, just like the file name is. 
# 
# Example: 
#    require DrgCms.model 'dc_page'
#

# When new plugin with its own DRG forms is added to application, path to
# forms directory must be send to DrgCms module. Paths are saved into @@paths hash variable. 
# 
# Adding path is best done in plugin mudule initialization code.
# 
# Parameters:
# [path] String. Path to forms directory
# 
# Example:
#    # As used in MyPlugin plugin.
#    require "my_plugin/engine"
#    module MyPlugin
#    end
#
#    DrgCms.add_forms_path File.expand_path("../../app/forms", __FILE__)
