Public Sub SetZone(zone As Integer)
This procedure is called by HomeSeer for infrared plug-ins that support zoned output. It is called usually just prior to a PlayIR command so that the output zone may be set before one or more PlayIR commands are processed. After setting the IR output zone to the indicated zone number, do NOT restore the infrared controller to a default zone as more than one PlayIR command may be sent. SetZone will be called by HomeSeer each time the zone output is to be changed/set.
