I finished making the tree, and I added more shapes into shapes.py as I

felt like they were okay enouh for now.

Something I am wondering about is if there is some sort of way to
"mirror" lines of code, because of the way that the turtle draws, it
would be nice to only draw half of something, and then have it finsish
by mirroring, like a loop but in reverse order (at least for things
that are symmetrical).
