[lkb] Morphological preprocessors

Hello,

I have a student working on an LKB grammar for Lillooet,
and now additionally working on a morphological analyzer
(initially in XFST) for that language.  We'd like to know
what the state of the art is for connecting external 
preprocessors to the LKB, as well as for going the other
direction and sending LKB generation output through the
FST to produce surface forms.

Thanks,
Emily
