Hmm, this is certainly interesting but not quite what I had in mind - I was 
thinking rather that bitbake-layers would be extended and it would be an 
explicit operation to add a layer from the layer index + all of its 
dependencies. We can of course also have something semi-automatic like this 
class, but the manual tool ought to come first IMHO (which the class could then 
make use of).

Cheers,
Paul
