/*
	make  layers shy based on regular expression text matching
	no known way to create a selection from script so hiding layers and then manual selection
	is the only simple way
	
	contains presets dropdown for selecting AECollada 1.1x imported faces and vertices(solids and nulls)
	uses javascfript regular expression syntax
	
	Dec 10 2011 - preserve and restore shy setting buttons, no filter if text empty, help tips
	Dec 14 2011 - restore not working, not all layers have id so use name instead, dont process null value dropdown
						no way to get layer id and names can repeat so use layer index with limitation 
						that no layers can be added or removed between a preserve and restore action
						note: layer id is available in SDK so maybe limitation of cs3 vs cs4/5/5.5 scripting?
						plan: use layer name unless repeating names found if so use index
						text search method only works the first time, use match instead
