 -------------- ---     --------

 01/15/12 11:12 jec      revisions for Gen2 framework

 11/07/11 11:26 jec      made the queue static

 10/30/11 17:59 jec      fixed references to CurrentEvent in RunTemplateSM()

 10/23/11 18:20 jec      began conversion from SMTemplate.c (02/20/07 rev)

 Function

     InitMorseElementsService

 Parameters

     uint8_t : the priorty of this service

 Returns

     bool, false if error in initialization, true otherwise

 Description

     Saves away the priority, sets up the initial transition and does any

     other required initialization for this state machine
