# This decorator is intended to be applied at the class level on model classes so that their state can be instantiated
# at creation time via keyword arguments.
#
# This decorator assumes that the model class has a swagger_types attribute which describes all of its available attributes to
# be set and that the keyword arguments passed match these attribute names. No type checking is currently done.
#
# Additionally, providing unrecognized keyword arguments (i.e. they do not match any swagger_type defined attribute) will result in
# a TypeError being thrown.
