/* File: ManageNumbers.cpp

Description: Example C++ program to demonstrate use of test main program
invoked with the compile flag "-DMAIN".

Main defined at compile time to be used to test classes.

Library generation and makefile compiles will not change and 
code will be compiled as usual.
Regular compile:     g++ -c ManageNumbers.cpp
Compile for testing: g++ -c -DMAIN ManageNumbers.cpp
