Hopefully-meaningful Metrics

A quick hack based on Michael Feathers' recent work in project churn and complexity: http://www.stickyminds.com/sitewide.asp?Function=edetail&ObjectType=COL&ObjectId=16679&tth=DYN&tt=siteemail&iDyn=2

Usage

chuggle /path/to/git/project

For now it just dumps out a hash of churn + flog metrics
