[Developers] mjt script to display any topic with a specified date

[Nick Thompson]

you can do this by wrapping the mjt.task inside a mjt.def.  when you invoke
the function created by mjt.def, it will fire off the subquery.  so you
can't put the mjt.task inside a mjt.for loop, but if you put the task
inside a mjt.def and call that function inside your for loop, it should
do the right thing.

i don't have good examples or documentation of this on mjtemplate.org yet,
but i've used it quite a bit.
