//Kris:
//This is the plan for game time...
//Game time should be restricted to outside code.	Think of it as encapsulation.	Anyway, using these
//simple functions, you will be able to change the amount of time that passes per frame.	The gameloop will
//automatically update the clock once per cycle, regardless of the mode you are in.
//This does pose potential problems in modes such as the editor, or similar where time shouldn't pass, and
//isn't currently handled.	The best thing to do in these cases is call the PauseGame() function when entering
//such a mode, and UnPauseGame() when finished.	Everything will be restored just the way you left it.	This
//is much simpler to handle in the overall scheme of things.	

//PAUSE FEATURES
//Pauses and unpauses the game.	It sets and clears a flag which preserves the time rate.

//USING TIME COMPRESSION
//Allows the setting/changing/access of time rate via predefined compression values.
//These functions change the index in giTimeCompressSpeeds which aren't in any
//particular mathematical pattern.	The higher the index, the faster the time is processed
//per frame.	These functions have their limits, so game time will also be between 
//TIME_COMPRESS_X1 to TIME_COMPRESS_X8 based in the laptop time compression.

//Note, that changing the clock resolution doesn't effect the amount of game time that passes per
//real second, but how many times per second the clock is updated.	This rate will break up the actual
//time slices per second into smaller chunks.	This is useful for animating strategic movement under
//fast time compression, so objects don't warp around.
