Add Initialization and Finalization methods for the Printer pass,

Browse Source 
to print various things on a module-by-module basis (currently, only the

Don't print < > around names. The assembler can't take it.

Print pseudoinstructions only as comments. The poor little assembler can't
take that, either.
