Implementing Polymorphism

/* The given C sharp example decalres abstract class Shape
* that implements polymorpism by overloading and
* overridding methods. The clas Shape2 consists
* of a virtual method ShapeType(). The method
* CalculateArea() is implemented twice by having
* different signatures and different return types.
* The class Square inherits the base class Shape2
* and overrides the base class method called ShapeType().
* The main() method creates an instance of the derieved
* class Square and the base class Shape2. the instance
* of the base class Shape2 invokes the method
* CalculateArea(). Depending on the parameter that
* the method CalcualteArea() takes, the apropiate
* method is called.
