/* ----------
	CodeBank - textlayer.js

	This code uses CSS to display a text message when the user rolls over an image.

    Revisions to Included File:
        The text to be displayed in the rollover must be placed in the file where it is to be displayed.
		The text must be wrapped in a DIV tag that starts with ro_
		If this text is custom formatted, change the CSS to reflect that.
