 * purpose: start up code to bootstrap initialization of kaMap within
 *          the sample interface.  Examples of using many parts of
 *          the kaMap core api.
 *
 * purpose: This is the sample ka-Map interface.  Feel free to use it 
 *          as the basis for your own applications or just to find out
 *          how ka-Map works.
