Detailed Description

This object as a way to properly control animation and other effects in our scene relying on the "timing" in the game.

Every frame of the game, we update this object with a snapshot of the current clock of the CPU in order to create a delta (differential) with the last clock snapshot. This delta controls the movement of the objects in our gameworld.

To make this object more platform independent, feel free to investigate using the SDL timer functions

Note that on some newer multi-processor systems, the QPC doesn't always cut the mustard. Depending upon your app, the resolution of timeGetTime() might be enough for your object animation...

It really just takes some experimentation folks..
