Spank Ministry

Or what I like to call my "Ruby Litmus Test."  Probably once every few months, I need to rename a bunch of files and I look for the quickest and easiest way to do it.  The first time, I wrote a script in Ruby, but I inevitably misplace or delete it by the next time, so I just rewrite it.  Hopefully, my current one is better than the one I started with, this is probably the third or fourth iteration.
