Creates Cluster native interface object.
Parameters
----------
transport_inst : :class:`~ieee488_2.transport`
Transport class responsible for the lowest level of communication (e.g. ethernet).
debug : int
Debug level (0 = normal, 1 = no version check, >1 = no version or error checking).

Raises
----------
Exception
Debug level is 0 and there is a version mismatch.
