+ * Creates all the demo application tasks, then starts the scheduler. The WEB
+ * documentation provides more details of the standard demo application tasks.
+ * In addition to the standard demo tasks, the following tasks and tests are
+ * defined and/or created within this file:
+ *
+ * "Check" task - 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.
+ *
+ * "Reg test" tasks - These fill the registers with known values, then check
+ * that each register still contains its expected value. Each task uses
+ * different values. The tasks run with very low priority so get preempted very
+ * frequently. A register containing an unexpected value is indicative of an
+ * error in the context switching mechanism.
