Dojo afterOnLoad

For some Dojo widgets, it is necessary to take advantage of a feature that was introduced in Dojo 1.2 to allow an application to get a callback when all of the dojo.requires() that are needed by the application are available.

The Dojo technique involves setting:

djConfig = { afterOnLoad: true );

and then within the onLoad callback:

MyClass = function() {};
MyClass.prototype.onLoad = function() {

   dojo.addOnLoad(function() {
      // Most initialization logic happens here
      // Don't want this logic to run until after
      // all of the Dojo modules we need have been loaded.
