// Contract: roll : void -> int
// Purpose: returns a pseudo-random roll
//          of this numSides-sided dice
//          instance, returning a value
//          between 1 and numSides (or,
//          in the interval [1, numSides] )
//
// Examples: (OK, being random, this is tricky!)
//          for a Dice instance:
//             Dice myDie(3);
//          myDie.roll() will return 1, 2, or 3
