Move TemplateIO here. It's intimately tied to the ... (quixote/_py_htmltext.py)

Update of /home/cvs/quixote
In directory hewson:/tmp/cvs-serv20496

Modified Files:
	_py_htmltext.py 
Log Message:
Move TemplateIO here.  It's intimately tied to the htmltext framework
now.  Simplify TemplateIO since it's no longer user visible (well,
unless you work hard to find it).
