** Image Map Captions.
Where the image has been assigned an image map captions may be assigned for each image map area.
The caption elements must be defined in the HTML code nested in a 'wrapper' DIV and must be assigned a common class name.
The 'wrapper' DIV must be assigned a unique ID name defined in the Captions option 'WrapperID'
and the common class defined in the Captions option 'CommonClass'.
The default condition is to display captions centered in the 'wrapper' DIV
however where the Captions option 'Sticky' is specified as false the caption will be displayed ajacent to the map area.
The script assigns a CSS style position of 'absolute' and positions each of the the caption elements,
the size, appearence and z-Index must be specified by CSS class rule.
