[Grace-core] filling in the gaps

[James Noble]

Hi all

over the next day or so we'll be filling in the gaps in the grace definition

I've just put something on control structures up on the wiki 
https://projects.cecs.pdx.edu:8443/~black/NewOOL/index.cgi/wiki/SequentialControlStructures

hope to do something on Collection literals and Syntax soon, and we hope
to put up something coherent about objects & classes.

At which point we should be pretty much done with enough to talk about in the workshops next week.

Our current (rough outline) agenda for those is here:
