Add unimplemented exception to the API
Add unimplemented exception to the API

Not all the API command are implemented it would be better that the user
would receive an error if it tries to call an unimplmeneted API call.

This adds an unimplemented_exception that would be thrown when an API
call is not implemented.

The unimplemented method, simply throws the exception.
