Identifying point goes direct to metadata display
The user should be able to click on a point (and maybe a polygon) with in the
map viewer and have the metdata be displayed for that selected element.

Queryable map layers can now be selected from the map and the results will appear in a popup window.
The selection mechanism has been designed so that you can draw a box to query or simply click a point. The point-based queries incorporate a few pixels of tolerance so that you don't have to click on the precise pixel.
FYI, the mechanism for communicating b/t client and server goes like this:
1) user clicks map to query which triggers the client to send a request including the query layer and the extents
2) A jsp proxy page recieves this request, passes the request to geoserver's WFS dispatcher.
3) Jsp page transforms the wfs response (a gml document) into html and returns to client.
