 *  Use this program with a virtual dimmer as the master for best results.
 *
 *  This app lets the user select from a list of dimmers to act as a triggering
 *  master for other dimmers or regular switches. Regular switches come on
 *  anytime the master dimmer is on or dimmer level is set to more than 0%.
 *  of the master dimmer.

******************************************************************************
 *                                Changes
 ******************************************************************************
 *
 *  Change 1:	2014-10-22 (wackford)
 *		Fixed bug in setlevelwhen on/off was coming in
 *
 *  Change 2:	2014-11-01 (wackford)
 *		added subscription to switch.level event. Shouldn't change much
 *		but some devices only sending level event and not setLevel.

  Other Info:	Special thanks to Danny Kleinman at ST for helping me get the
				state stuff figured out. The Android state filtering had me 
                stumped.
