IT201 Project 4 Spencer Korman

My Sprint 3 builds upon Sprint 2.  In sprint 2 I added a rewind feature that allowed Users to rewind a given number of seconds to what strokes were previously on the screen.  In sprint 3 I built upon this by adding 3 more features.  1, Setting old primitive strokes to new Prefab strokes. 2, Animating the primitive strokes with 2 animations each, and 3 Adding UI controls for controlling the animations.  A Lot of time was also focused into tying the new animation system into the pre-existing rewind system
