/**
 * <p>
 * A special version of the CurrentDicePile that is used to represent constants.
 * In most cases this can be treated like a one sided die but there are a couple
 * differences:
 * 
 * <p>
 * 1. the display is just a number; no "dN" suffix
 * 
 * <p>
 * 2. The button is only made invisible if the control is cleared.  This allows
 * the user to enter negative nubmers.
