/****************************************************************************
Function
ES_Run
Parameters
None
Returns
ES_Return_t : FailedRun is any of the run functions failed during execution
Description
This is the main framework function. It searches through the state
machines to find one with a non-empty queue and then executes the
state machine to process the event in its queue.
while all the queues are empty, it searches for system generated or
user generated events.
Notes
this function only returns in case of an error
