[tahoe-dev] darcs patch: Add statistics module

[Shawn Willden]

Note that this is meant not as a serious patch but as a test.  I'm learning 
Python, Trial, DARCS, Tahoe coding structure and conventions, etc.  All 
suggestions for improvement greatly appreciated.

One thing I learned already is that "darcs send" actually e-mails the patches!  
I knew it could, but I was expecting it to ask me whether or not to send it.  
Apparently, if you don't want it sent, you shouldn't type in a target e-mail 
address.

	Shawn.
