/*
* 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:
*
* "Web server" - Very basic demonstration of the lwIP stack. The WEB server
* simply generates a page that shows the current state of all the tasks within
* the system, including the high water mark of each task stack. The high water
* mark is displayed as the amount of stack that has never been used, so the
* closer the value is to zero the closer the task has come to overflowing its
* stack. The IP address and net mask are set within FreeRTOSConfig.h.
*
* "Check" task - This only executes every five 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. While no errors have been
* discovered the check task will toggle an LED every 5 seconds - the toggle
* rate increasing to 500ms being a visual indication that at least one task has
* reported unexpected behaviour.
*
* "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.
