Added a gitignore for vim swp files and got the
gimp_run function back into a working state
Got the recursive generator for walking through a
tree structure working
Changed the name of the class from golden_tree to
Tree.  It makes more sense given the rapidly
expanding ideas of what I want to implement..
Added logic for getting the end point of a new tree
branch.  I have no idea if it is correct.
Added some magic to change the slope of the lines.
It doesn't work but at lease now it looks like some
sort of tree is being drawn.  Now it is just a matter
of getting the angles right and adding features! :D
