Brighten When It Opens

/**
 *  App Name:   [Scene Machine] Brighten When Open
 *
 *  Author: 	Todd Wackford;  modified by Bruce Ravenel
 *				twack@wackware.net
 *  Date: 		2013-06-14
 *  Version: 	1.1
 *  
 *  Updated:    2013-07-25
 *	Modified:	2015-02-13
 *  
 *  Change #1	Fixed bug where string null was being returned for non-dimmers and
 *              was trying to assign to variable.
 * 
 *  Change #2	Updated setLevel setion to work with bulbs that were not defined as type "Dimmer Switch"
 *
 *	Modified	Now triggered by a contact opening, and temporarily sets dimmers to 100%
 *  
 *  
 *  This app lets the user select from a list of switches or dimmers and record 
 *  their currents states when a door opens, and then restores that state when   
 *  the door closes   
 *
 *  Usage Note: GE-Jasco dimmers with ST is real buggy right now. Sometimes the levels
 *              get correctly, sometimes not.
 *              On/Off is OK.
 *              Other dimmers should be OK.
