----------------------------------------

Hi Balaji:

In order to maintain existing style, could you remove the param from the ctor 
(since it accepts null anyway) and add method .setGadgetFeatureRegistry()?

> Need convenience method to get all required features of a gadget.

> Right now if we want to find out all the required features for a gadget, we 
> have to do the following
> gadgetFeatureRegistry.getFeatures(gadget.getSpec().getModulePrefs().getFeatures().keySet())
> This means that any component that needs to get to the list of required 
> features, has to get access to the gadget feature registry.
> It would be nice to have a convenience method in Gadget that would give 
> that...
> ie gadget.getAllFeatures();
