Removed cwbhost/cwbport logic from code, will let EdgeFactory deal with that. Rewrote the get_tag routine to use strings, which only work if the string is spliced to exactly 12 characters.  Rewrote the get_tag routine to remove the sequence code.  Rewrote the sequence code for data packets to use class variables. Other cleanup, especially comments.

Refactored to clean things up and improve readability,  added comments.  Committing now,  because it mainly works.
