 * @fn          AssertHandler
 *
 * @brief       This is the Application's callback handler for asserts raised
 *              in the stack.  When EXT_HAL_ASSERT is defined in the Stack
 *              project this function will be called when an assert is raised, 
 *              and can be used to observe or trap a violation from expected 
 *              behavior.       
 *              
 *              As an example, for Heap allocation failures the Stack will raise 
 *              HAL_ASSERT_CAUSE_OUT_OF_MEMORY as the assertCause and 
 *              HAL_ASSERT_SUBCAUSE_NONE as the assertSubcause.  An application
 *              developer could trap any malloc failure on the stack by calling
 *              HAL_ASSERT_SPINLOCK under the matching case.
 *
 *              An application developer is encouraged to extend this function
 *              for use by their own application.  To do this, add hal_assert.c
 *              to your project workspace, the path to hal_assert.h (this can 
 *              be found on the stack side). Asserts are raised by including
 *              hal_assert.h and using macro HAL_ASSERT(cause) to raise an 
 *              assert with argument assertCause.  the assertSubcause may be
 *              optionally set by macro HAL_ASSERT_SET_SUBCAUSE(subCause) prior
 *              to asserting the cause it describes. More information is
 *              available in hal_assert.h.
 *
 * input parameters
 *
 * @param       assertCause    - Assert cause as defined in hal_assert.h.
 * @param       assertSubcause - Optional assert subcause (see hal_assert.h).
 *
 * output parameters
 *
 * @param       None.
 *
 * @return      None.
