[texhax] binary symbol needed

[Barbara Beeton]

gerree,

    I'm in need of a binary symbol called
    interior product ... I have searched through the many
    manuals ... could not locate it ... standard math symbol?

this symbol exists in unicode; see the
chart at
  http://www.unicode.org/charts/PDF/U2A00.pdf
where it appears in position 2A3C.  (some
mathematicians prefer the upright leg to be
longer than the one on the bottom; that's
a recognized variant.)

however, i don't know of current availability
in any tex font, although this is being worked
on.  for the present, i suggest hacking it
together from a vertical and a horizontal line
in a box, making that \mathbin, and calling it
\intprod (that's what it will be called in the
stix font, once latex support is created).

    Please email your response to myself and Professor Kohn.

done.
