I made a shapes.py file to keep my good shapes once I've finished them.

I made a draw_leaf function and put it into a shapes.py because I think
the leaf is pretty good. I started trying to draw the trunk / branches /
roots of the tree, but it's not finished so I didn't put it into
shapes.py yet.

It was easy to make the leaf, I used two 90 degree arcs and a straight
line between them equal to the chord length.
I was trying to make branches with more branches coming off of them,
but it was difficult to make the branches repeat the way I wanted to,
so I am now just trying some basic rods for the main branches, and then
once I figure out the loops for that I will figure out how to do loops
to make little branches off of the main branches.
