Commented out Washington DC from the available regions. The region is too small to click without zooming. Note ... I need to enable zooming.
Added data ensurances to the abbreviation. Added hints.
Moved the map from outside the question element, to inside it. This assures that the hints will show below the map. Fixed the method to reset the map, so that it re-shows after the question has been refreshed. Also added a method to return the hints.
