* Creates all the demo application tasks, then starts the scheduler. The WEB
* documentation provides more details of the standard demo application tasks.
*
* A "Check" task is created in addition to the standard demo tasks. This
* only executes every three seconds but has a high priority to ensure it gets
* processor time. Its main function is to check that all the standard demo
* tasks are still operational. If everything is running as expected then the
* check task will toggle an LED every 3 seconds. An error being discovered in
* any task will cause the toggle rate to increase to 500ms.
