/****************
getDataReturnText(url, callback)
	** Uses the GET method to get text from the server. **
	Gets text from url, calls function named callback with that text.
	Use when you just want to get data from an URL, or can easily
	encode the data you want to pass to the server in an URL, such as
	“http://localhost/script.php?a=1&b=2&c=hello+there”.
	Example: getDataReturnText(“http://localhost/data.txt”, doWork);
	Here, the URL is a string, and doWork is a function in your own
	script.
