command parser skeleton in place
Switched to subparsers from getattr
Added subcommand 'clear'

Resets json to basic state, future option will allow deletion of .conf (maybe just .conf/*.json)
Started work on create and then remembered to commit in small increments, but before
then managed to get in all arguments, now just need to handle flow control and insertion
Add and drop functionality now in place

NOTE: Very basic, probably error prone, also ugly, but WORKING
Cleaned up some of the docs
Merge branch 'cw'

cfgen.py has basic functionality, merging back into master

Monica's been busy, if I don't merge it's going to be a nightmare when
I do.
