* Description: This is the 'standard' C startup entry point.  main() does the following:
*
*              1) Outputs a 'sign on' message on the serial port
*              2) Initialize uC/OS-II
*              3) Create a single task which will create the other application tasks.
*              4) Start uC/OS-II
*
* Arguments  : None
*
* Returns    : main() should NEVER return
*
* Note(s)    : 1) It is assumed that interrupts are DISABLED when main() is called.  Interrupts will
*                 be enabled by the first task that uC/OS-II starts.
