'Creates a layer from its config.
This method is the reverse of `get_config`,
capable of instantiating the same layer from the config
dictionary. It does not handle layer connectivity
(handled by Container), nor weights (handled by `set_weights`).
# Arguments
config: A Python dictionary, typically the
output of get_config.
# Returns
A layer instance.'

    return cls(**config)
