Class ID

Implementation note:

An ID exists within a particular IDSpace, and is generated by a particular Server. It holds onto the space and the Server which created it, along with a number identifying the ID uniquely. If mySpace is nil, then the ID is in the global IDSpace. If myBackend is nil, then this ID was generated by the current Server (unless myNumber is negative, in which case it is considered to have been generated by the "global" backend). If myBackend is non-nil, then myNumber must be non-negative.
