Design and implement a class called MonetaryCoin that is derived from the Coin class included in the SOFT7004 Lab 3 folder. Store a value in the monetary coin that represents its value and add a method that returns its value. Create a main driver class ( called MonentaryCoinTest) to instantiate and compute the sum of several MonetaryCoin objects. Demonstrate that a monetary coin inherits its parent's ability to be flipped. Remember to include the necessary setters and getters.
