////  Name: main
////
////  Purpose: The entry point into the Exhibit #2 Application.
////           main() performs basic initialization, including connecting
////           to an EVM-DM642.  main() then passes control to RunApp(),
////           which actually executes the application.
////
////  Input  Parameters:
////      argc - number of inputs to the program, plus 1.
////             <= 2
////      argv - the inputs to the program, in "string" form.
////
////  Output Parameters: none
////
////  Return Value(s)  :
////      0 - in ALL cases.
