/**
 * This example shows how to create two different groups of Overlays from an XML file and display them on screen.
 * Notice that the code itself does almost nothing. All of the positioning and styling of the Overlays is handled
 * in the OverlayExample.xml file.
 * 
 * The first group contains an OverlayStat with the label "SCORE: ".
 * The second group contains two Overlays: an OverlayString with the text "HEALTH: " and an OverlayBar.
