application, and a more comprehensive test and demo application.  The
mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting is used to select between the two.

If mainCREATE_SIMPLE_BLINKY_DEMO_ONLY is 1 then the blinky demo will be built.
The blinky demo is implemented and described in main_blinky.c.

If mainCREATE_SIMPLE_BLINKY_DEMO_ONLY is not 1 then the comprehensive test and
demo application will be built.  The comprehensive test and demo application is
implemented and described in main_full.c. */

smaller heap regions - in which case heap_4.c would be the more appropriate
choice.  See http://www.freertos.org/a00111.html for an explanation. */
