26		-1. Adding a function Area() with the same anatomy as Circumference() is easy, since it only requires adding new code.
27		-1. Adding a new datatype, Rectangle, is more difficult because it requires touching existing code, namely any functions like Circumference() or Area() that need to be enabled handle this datatype.
