I've added most of this now:

   http://dev.w3.org/2006/webapi/WebIDL/#MapClass
   http://dev.w3.org/2006/webapi/WebIDL/#es-map-members

I haven't added the iterator type argument to [MapClass] yet.  Can you 
go into some more detail about how that would work?

The spec needs a bunch of updating for iterators defined by @@iterator 
anyway.


Please have a look at the new text and let me know if there are any issues.
