[IronPython] Template library

[Zach Crowell]

Wow, I'm a bit out of it today - didn't dawn on me to just walk through the re module sources, as that would be the normal thing to do.

Thanks Dino.  And maybe on a day when I'm more alert :)

According to the comment in re.cs this is "yes/no if group exists" and we
don't support it currently.  This might be rather easy to implement.

Hey Zach, if you fix it we'll accept the fix from you given that you
work  at MS :)  Either way I've opened a bug to track it:

I'll try and look at it before 2.6 is done but I'm busy w/ some
other stuff right now.
