/*
	The healer is a military creep whose job it is to heal other party members.
	
    The healer has the following states: 
        -deploying : the healer is heading to the checkpoint
        -escorting : the healer is escorting their squad to complete their mission
        -idling: the creep is awaiting further instructions
	
	The healer's memory is structured as follows:
		-spawn: spawn name
		-job: the creep's current task
		-checkpoint: the creeps current checkpoint #(if deploying)
		-military: true , boolean value to identify combat creeps
		-squad: the creep's squad

    NOTES:
