PyTREX feature complete

I've just release PyTREX 0.7.0 at

	http://sourceforge.net/projects/pytrex/

PyTREX now implements the entire TREX specification. There are a couple of
known bugs and no anonymous types are supported but everything in the spec
is implemented.

Interestingly, PyTREX was written almost entirely on transatlantic flights
between Boston and London (flying coach :-)
