Confusion over name, id, frame properties

There is confusion over what some of the properties are when they are returning a sting name, naif code, naif frame code. We should make this clear and consistent asap.

Possible Proposal:
xxxxx_name = returns a long name
xxxxx_short_name = returns an abbreviated short name
xxxxx_id = returns an integer
xxxxx_frame_code = returns a naif from code
