[DAS] Dalliance: a new genome DAS client

[Jonathan Warren]

This url list 150 das sources that implement cors - see traffic light  
on the end:

http://www.dasregistry.org/listServices.jsp?organism=any&CSName=any&CSTypes=any&capabilities=cors&labels=any&spec=any&cmd=find

You can check the headers responses for any of their valid responses.

If you  want some java code that adds this functionality to MyDAS I  
can send it to you...
