[Grace-core] inheritance for stateless traits and beyond

[James Noble]

Hi Kim & all

so on Kernan(1) - with auxiliary definitions below(2) - you get the following results.
If you have a local definition it overrides everything. 
Only if you don’t have a local definition, 
and you put code between the inherits statements
can you see the change in method binding.

2. you have to load the file: cut & paste doesn’t work (and won’t in the immediate future)
