# Note that adding a module using this method does not cause it to be used in the authentication
# process. That requires that the module be listed in the arguments passed to the 'devise' method
# in the model class definition.
# == Options:
# +model+ - String representing the load path to a custom *model* for this module (to autoload.)
# +controller+ - Symbol representing the name of an existing or custom *controller* for this module.
# +route+ - Symbol representing the named *route* helper for this module.

# +insert_at+ - Integer representing the order in which this module's model will be included
# All values, except :model, accept also a boolean and will have the same name as the given module
# name.
# == Examples:
# Devise.add_module(:party_module)
