 *
 *    Purpose:
 *       The file is a stub that allows the reader/programmer to extend
 *       the Control Unit within the Data Path Simulator, PathSim, to
 *       handle additional MIPS operators. The extension is accomplished
 *       through adding java code to the method execute. See the lab
 *       instruction comment given below.
