java.lang.ExceptionInitializerError workaround code: initialize some critical
parts of the (generate) namespace by generating a phrase (gram/nbar).
"fare (to do)" is essere-false.
add :activity=true implicatures: (not human and not body part)
houses are not activities.
restrict :mod of "fare (to make)" to avoid over-generation when :mod {:pred :bene} is specified, in which case the user wants a different form of "fare" than "fare (to make)".
add a "fare bene (to do well to)" test
add (defn sem [sign]): show semantics of given sign.
squash into workaround commit.
