Fixed a cross product bug where the vectors would return as zero dist, but now I need to fix the number of times I call calcInitVectors

It should only be called the first time through an iteration, NOT
completely throughout the phase when controlPoint == 1
Fixed the calInitVectors bugs.  All I need to do is add in the animation hack (because it takes a long time to load).
Fixed bugs with the double rail drawing to the best of my ability. Will run tests with all of the coaster again, and then wrap this up
Fixed some minor bugs in the code

1.  Fixed it so the the camera looks in the right direction.
2.  Fixed a bug where the camera randomly flipped due to an extra
initial Vector calculation call
3.  Fixed the track rail and line sizing to be nicer.
4.  Fixed my track a little bit
Fixed up the width between the two rails and rail sizes some more.
Modified the assignment slightly, and added in the animation.
Added the README
