Digger - a D archeology tool

[Vladimir Panteleev]

https://github.com/CyberShadow/Digger

This tool can build arbitrary D revisions from git (currently up 
to about 2 years ago), and automate git-bisect to find out which 
pull request changed/broke something.

This tool is the continuation of my D-dot-git project, and is 
meant to be a companion to Dustmite when dealing with regressions.
