[logon] removing ‘uw/mmt/’ from the LOGON tree

[Stephan Oepen]

hi emily,

i am preparing a new release of the LOGON tree for the summer, and
among other things i would like to reduce storage requirements.  the
MMT directory appears to not have received updates for the past three
years, and i think i vaguely recall you have gone over to a different
set-up for your end-of-class MMT demonstrations.  would you mind if i
purge ‘uw/mmt/’ from the LOGON tree now?

with thanks in advance, oe
