I really hope I'm doing this correctly.  Following directions on http://stackoverflow.com/questions/4114095/revert-to-previous-git-commit to reset back tot he commit before I started messing arond with the qe_develop branch (f1a1d014e8ad441cb29a03eb55e273ac220b1e6d).  Before I did this I created a new feature branch qe_develop_brian_1.0.5 to preserve my work and continue on with my modified VCFDumper that will calculate the aggregation I was interested in.  I doubt that branch will ever be merged but hopefully this commit (and that branch) will show Denis what he needs to work on from a plugin API perspective.  It's pretty difficult right now to write plugins but with some simple tweaks I think it could be made much more functional.
