Added and tested two functions to create ellipses

So far the biggest sticking point has been the planning, mostly from the standpoint of
designing a drawing that I will realistically be able to create with turtle. I want to make
a dog, so I was going to make a pointer (my dog) holding point, but the curves were
complex and I couldn't quite figure out how I wanted to integrate iteration into that design.
I've since decided on a dog's face, where I can use a lot of the same shapes in a variety of
locations, so I'm hoping that continues to work. The ear() and face() functions that I have
right now generate two different forms of ellipses, one sort of football-shaped, the other much
longer and narrower, proportionally.
