PyTREX 0.6.0 released

I've just released PyTREX 0.6.0 at http://pytrex.sourceforge.net/

This release implements the concepts introduced in sections 1 through 10 of
the tutorial. 

Changes: Added support and tests for pattern inclusion, grammar merging
(partial), named datatypes, "not", "difference", "choice" in nameclasses,
"nsName", "anyName", "notAllowed", namespaces, qnames, trex namespace.
Changed py file to being importable. 

As always, let me know if you encounter bugs.
