Registers an object with the Keras serialization framework.

This decorator injects the decorated class or function into the Keras custom object dictionary, so that it can be serialized and deserialized without needing an entry in the user-provided custom object dict. It also injects a function that Keras will call to get the object's serializable string key.

Note that to be serialized and deserialized, classes must implement the get_config() method. Functions do not have this require
