/**
 * A MonitorInfoBlurb is an extension of the GenericPopUp used to show static information (vs. interactive context
 * menus). It accepts some text (text), an item to link to to (target), and a specification of which side of the target
 * to appear on (direction). It also sets the GenericPopUp's color to black, to differentiate itself from a menu.
