Global variable visibility

[David LeBlanc]

Ah, the commands.Db idiom wasn't one I thought of. My "punt" was to create
an Initialize method in the commands.py file and call it with Db as a param:

Db = None

def Initialize(database)
	global Db
	Db = database

commands.Db is obviously simpler and more obvious too.

Not exactly sure what you mean by rebinding. Would (in commands.py) Db =
__main__.Db be a rebinding or another reference?
