Please star this issue if you would find a "parsed" event as described in the 
EGeoXml documentation useful.  It doesn't exist at present, trying to gauge 
interest/usefulness.

"parsed" Event

EGeoXml throws a "parsed" event when the parsing is complete.
The EgeoXml.parse() operation is asynchronous because it uses GDownloadUrl(), 
so if you have code that should only operate after the markers etc. have all 
been created, then you'll need to listen for that event.
