Expanded docs
Register a handle for Django ValidationExceptions (allows us to use django validators by default), add baldr ResourceField and ResourceListField to supported mapped fields. Added mapping of attributes from model and validators . Allowed an override for the resource_type_name onto the model_resource_factory
