Nathan Binkert 2771abb6ed Totally re-do/reorganize the python part of the statistics code
Make the database creation/removal/cleanup code use python
Make formulas work with the database
Add support to do some graphing, but needs more work
Still need to work on vectors, 2d vectors, dists and vectordists
