[Mapbuilder-devel] Asynchronous document loading

[Adair, M. <Mike.Adair@CCRS.NRCan.gc.ca>]

We now have asynchronous document loading!  The main changes are in
ModelBase.js and involve some of the initialization event sequence handling,
but I think I've been able to simplify it as well. I'll be writing more docs
about it soon.  It does allow us to do a better job in handling document
loading for both error handling and state changes in the document.

I haven't done any timing tests but it might appear that the page loads
slightly quicker, but not much so.  I've tested both synch and asynch
loading with all pages in /demo without prolem but try it out, and let me
know of any problems encountered.
