	// summary:
	//		Check if a parameter is ready, and if not,
	//		"do later". doLater will ping the parameter
	//		until it evaluates to something (truthy).
	//		It thens calls the caller with original
	//		arguments, using the supplied context or 
	//		window.
	//	description:
	//		dojox.timing.doLater(conditional) is testing if the call
	//		should be done later. So it returns
	//		true if the param is false. 
	//	arguments:
	//		conditional: anything
	//			Can be a property that eventually gets set, or
	//			an expression, method... anything that can be
	//			evaluated.
	//		context:	Object
	//			The namespace where the call originated.
	//			Defaults to global and anonymous functions
	//		interval:	Number
	//			Poll time to check conditional in Milliseconds 
	// example:
	//		| setTimeout(function(){
	//		| 		if(dojox.timing.doLater(app.ready)){return;}
	//		| 		console.log("Code is ready! anonymous.function SUCCESS")
	//		| 	},700);
