** Class: CITC 1310 P01
** Program Name: digiRPS (Digital RPS/Rock Paper Scissors)
** Program Description:
**          This progam offers two simulations of a game of Rock-Paper-Scissors.
**          The user can choose between Easy and Hard difficulty; the former
**          game mode pits the user against a non-player character (npc) who
**          makes choices randomly, while the latter uses an AI that attempts
**          to beat the user with strategic planning and manipulation.
