This function is used to suspend an application's display processes without actually exiting. It clears the display, initialization, and frame functions (set by CAVEDisplay, CAVEInitApplication, & CAVEFrameFunction), and then has the display processes call function. This routine will not return until after function has been called. Note: you do not have to call CAVEStopApplication before exiting a CAVE program, unless you want the graphics processes to call a "clean-up" function.
