Revision 455

"normalized" files:
- (c) header on all files
- standard order of preamble lines:
	1. (c) header
	2. package PACKAGENAME;
	3. short summary of the package (pod's NAME section)
	4. use - pragmatic modules
	5. use - standard perl modules
	6. use - CPAN modules
	7. use - webwork modules
- ALWAYS use strict and use warnings
- use "use base" rather than "our @ISA"
so now we can be happy.
