/* This should be called in the main function above.

* This function sets the random seed for the game using srand(seed).
* One incomplete way to do this is given below: start a Timer and sample it
* to get a seed. The problem is that the same exact time will be read
* every time you reset the mbed.  You need to add code to introduce
* variability into when the timer is stopped.  An easy way to do this
* is to get the user to press a push button to stop the timer at a random
* time.  You can print a prompt to the screen to ask the user to push
* any button to start, then run an infinite while loop that waits for a push 
* button press to break. The Timer is then stopped and read and elapsed time
* used as the seed. (This requires using read_inputs() into a GameInputs variable.)
