    This program demonstrates how some of the functions in the
    kishio library can be used.
    
    Updated 2014-02-11 to add test for:
        char getChar(const char*, const char*)
*/

// This was compiled by placing kishio.h and kishio.cpp in the 
// same directory and using the following command to compile:
//     g++ -Wall -o testKishIO testKishIO.cpp kishio.cpp
//
// The program can then be run using this command:
//     ./testKishIO
//
// If using an IDE, just add kishio.h, kishio.cpp, and
// testKishIO.cpp to the same project and compile and run.
