[OpenLayers-Dev] OpenLayers.Strategy.Grid

[Zac Spitzer]

I got it working :) works really well

I just pulled out the createURL from TMS and plugged it in

the whole reason I was interested in the grid stuff was to allow the requests
to become static to elimate any server side spatial processing
and use just use static files

this is scaleable as all you need is a webserver

the bbox is only required for the initial call, subsequent requests
don't require any server

once the cache is seeded, which i would do using my mapguide tile
seeder, the bbox urls
could be removed
