Console test program needs to be updated to C++

[Norm Olsen]

As the CS-MAP library was originally developed in C, the console test program was also written in C, and has remained in that form. As more and more C++ has crept into the CS-MAP library, it now becomes very inconvenient for the console test facility to remain a C program. It's easy to call C from C++, but rather painful to call C++ from C.
