Support for ImageOverlay of Products
------------------------------------

                 Key: OODT-437
                 URL: https://issues.apache.org/jira/browse/OODT-437
             Project: OODT
          Issue Type: New Feature
          Components: file manager
            Reporter: Paul Ramirez
             Fix For: 0.5


Support a product type policy that would capture enough information to do 
ImageOverlays. This would minimally require policy to capture the bounds of the 
image. Once this was in place one could get the metadata for the product (using 
curator services) and use these fields to place the image on a map. 

If we really wanted to extend this we could create a product preview service 
that took in the product id and returned either a leaflet map, open layers map, 
or kml.

http://localhost:8080/preview/{product_id}?format={format}

Where {format} is one of kml, openlayers, or leaflet. For openlayers and 
leaflet I would imagine one would return the HTML to represent the map along 
with javascript required to do the image overlay (e.g. 
http://leaflet.cloudmade.com/reference.html#imageoverlay). For the KML this 
should just return this 
https://developers.google.com/kml/documentation/kml_tut#ground_overlays.
