2.3.2.2 Get Timed Key Response (#C)

The Get Timed Key Response pauses Cogsys until the subject presses a key. If no character is pressed within a given timelimit, TIMEUP_RESP_CHAR is written as the key pressed. Either way, the Cogsys response key and response time variable are updated.

If the BREAKOUT_CHAR key is pressed, the experiment is terminated.
