is a 5% commission for instructors that get students to book additional lessons.

	note that each entry except the last one needs to be followed by a comma
	
	an example of each, in the same order:
	new promoObj("test10percent", "promo", "percent", "all", "all", 0.1, "", ""),
	new promoObj("test5bucks", "promo", "dollar", "all", "DW_only", 5, "", ""),
	new promoObj("test3per", "type"=>"per_person", 3)

	Not Active:
	new promoObj("Mark", "referral", "percent", "all", "all", .03, "", ""),
	new promoObj("Jackson", "referral", "percent", "all", "all", .03, "", ""),
	
	The format is:
	(name, promoClass, type, program, usage, amount, emailSubject, notes)

	promoClass   = either promo or referral
	type    = dollar or percent
	program = camp, lesson or all
	usage   = DW_only, SM_only, VEN_only or all
