Support round-robin for map sources #89

Open GoogleCodeExporter opened 8 years ago

RMCloudMadeMapSource.m and other support one fix URL per source. But e.g. 
CloudeMade is 
offering round-robin URLs:

The URLs for http://%@.tile.cloudmade.com/devid/1/%d/%d/%d/%d.png can be:
http://a.tile.cloudmade.com/devid/1/%d/%d/%d/%d.png 
http://b.tile.cloudmade.com/devid/1/%d/%d/%d/%d.png 
http://c.tile.cloudmade.com/devid/1/%d/%d/%d/%d.png 

This should improve loading performance . Would be great to have support for 
that generalized.

Andreas: I switched from a.tile.cloudmade.com to simply tile.cloudmade.com in 
r341. 

In http://developers.cloudmade.com/projects/tiles/documents they state that the 
explicit provision of a/b/c 
roundrobin is to get around connection limits in browsers. So this would impact 
us only if we were being limited 
by the number of simultaneous NSURL connections that Cocoa Touch allows to a 
particular host.

What change are you proposing? How would that make things faster?
