[alicebot-general] How interpreters handle multiple PATTERN <that> THAT <topic> TOPIC

[mehri]

Yea, saw that in your interpreter, just missed putting
in:

into my earlier email.  You didn't think I was smart
enough to think of those options on my own did ya' ;-)

I have modeled a great deal of my interpreter from
your java version.  I have on my to-do list to model
this as well.  Since the scope of my project is an
AIML C++ api, I will make methods on my builder class
that allow the api user to decide which to do and have
the "overwrite" be the default since currently that is
the way it does it.
