PROGRAM 6: ShapelyShapes.cpp
-------


Implement the Shape hierarchy below. Each TwoDimensionalShape should
contain the function getArea to calculate the area of the two dimensional
shape. Each ThreeDimensionalShape should have member functions getArea and
getVolume to calculate the surface area and volume of the three-dimensional
shape, respectively. Create a program that uses a vector of Shape
pointers to objects of each concrete class in the hierarchy.  The program
should print the object to which each vector element points. Also, in the
loop that processes all the shapes in the vector, determine whether each
shape is a TwoDimensionalShape or a ThreeDimensionalShape if a shape is
TwoDimensionalShape display its area. If a shape is a ThreeDimensionalShape,
display its area and Volume.


                               Shape
                            /         \
                           /           \
        TwoDimensionalShape             ThreeDimensionalShape
       /      |          \              /        |         \
 Circle     Quadrangle     Triangle     Sphere    Cube       Tetrahedron
            /        \
           /          \
         Rectangle   Square




As in previous assignments you are responsible in writing a "driver" program
that demonstrate your implementation of the above functionality and that
it works correctly.  The "driver" program is the main function.

OTHER REQUIREMENTS:
-------------------
 * Proper commented code

 * Modularized program

 * Good software engineering techniques, hints in text book.

 * You must submit at least the following files (i.e., all the files
   necessary to compile your program):

        README.txt
        ShapelyShapesDriver.cpp
        Makefile
 
 To submit the files, you will need to use the submit program.  Your files
 need to be under a common subdirectory called "1730_program6".
 
 Execute the below command line while in your home directory:
   submit 1730_program6 cs1730
 
 NOTE: you need to be LOGGED ONTO ajax when you execute the submit command.
