a method, save, that assigns the value of accumulator to memory
a method, recall, that assigns the value of memory to accumulator
a method, clearMemory, that assigns zero to memory
a method, getMemory, that returns the value stored in memory

Test your CalculatorWithMemory class by creating an object and calling its methods in the Main class.
