First tree

I've got a very basic tree to appear on Google Earth. It's not much to look at, but the code is finally starting to come together. I'm leaving for Chicago for the holiday weekend so I won't be able to get much done over the weekend, but I'll put the code up on github so you can have a look.

EDIT: the KML file testfile.kml in the phyloGeoRef directory on github has the test tree in it. Just copy that file into Google Earth and the tree should appear.
