Multi-Tree Mayhem?

New version of Treemaker. It's automatically set in a two-player mode, to test, so realize that you are taking turns placing seeds and then branches and such for alternate trees. The player turn switches when you place a knot (not a branch with a leaf or root or an additional leaf). Sunlight gathering finally actually works, but resources are not properly-balanced (I'm working on it... but I'll probably get all of the basic parts working first).
