  * Creates all the demo application tasks, then starts the scheduler.  The WEB

  * In addition to the standard demo tasks, the following tasks and tests are
  * defined and/or created within this file:
  *
  * "LCD" task - the LCD task is a 'gatekeeper' task.  It is the only task that
  * is permitted to access the display directly.  Other tasks wishing to write a
  * message to the LCD send the message on a queue to the LCD task instead of
  * accessing the LCD themselves.  The LCD task just blocks on the queue waiting
  * for messages - waking and displaying the messages as they arrive.
  *
  * "Check" hook -  This only executes every five seconds from the tick hook.
  * Its main function is to check that all the standard demo tasks are still
  * operational.  Should any unexpected behaviour within a demo task be discovered
  * the tick hook will write an error to the LCD (via the LCD task).  If all the
  * demo tasks are executing with their expected behaviour then the check task
  * writes PASS to the LCD (again via the LCD task), as described above.
  *
  * "uIP" task -  This is the task that handles the uIP stack.  All TCP/IP
  * processing is performed in this task.

	This code is commented out as the MAM does not work on the original revision

	the use of the MAM.

	Setup and turn on the MAM. Three cycle access is used due to the fast
	PLL used. It is possible faster overall performance could be obtained by
	tuning the MAM and PLL settings.
