Rain objects

Skull, Teapot, and Cube
HTML file containing <canvas>
Libraries from WebGL book
Object Selector

defaults to cube object without calling switchTo(STRING) function

STRING = ["SKULL", "TEAPOT", "CUBE"]
Renderable Model

Basically identical to the class provided by professor, except I spaced
it out for easier reading.
Camera

Again, similar to the professor's camera function but spaced out a
little bit easier to read. Modified getRotatedCameraPosition() to take
an array rather than just an angle. I was attempting to pass height and
depth parameters as well as an angle parameter in the tick() function to
allow the camera to move in all directions.
Main thread

I was trying to use this to perform animation while updating camera
location.
Alright so I looked over what is in Github, and decided we weren't really very far from Practice Assignment #3, so I torched what was up there and reloaded. Check Email for more verbose description of what's going on.
The rain functionality has been added.

It works well for the cubes, not so well for the teapots, and not at all
for the skulls. The speed and the distance between falling objects can
be changed relatively easily. Let me know if you have any concerns.

Merge of Ed's pull request I broke into a million pieces
