 * The following functions aid in the creation of Coremetrics data tags.
 *
 * 12/14/2009		JBowser		Initial multiclient library creation, with cmSetClientID
 * 02/09/2010		JBowser		Updated productViewTag, shopAction5 and shopAction9 categorization code to the follwing: 
 *											IF __cg value is provided (NOT NULL / NOT EMPTY / NOT ZERO) THEN use __cg value 
 *						   				ELSE IF catIDoverride NOT NULL THEN use catIDoverride
 *						   				ELSE use __cg
 * 02/23/2010		JBowser		Rolled existing library for 90252781 (fossil.com) into this multiclient library.
 *										Added latest IO code.
