Log message:
More progress on elimination tactics. They are now mostly complete, except for
the "big step elimination" rule, where we get the following unproved subgoals:
- A few wf subgoals for the "bindn {..sequent_bterm{0}}" in
pnm_core_judgments. Hopefully they will go away at the same time we fix them
for the intro rules.
- The subgoals corresponding to the "subtheory" cases. Currently the
assumptions we generate for subtheories in these "big step elimination"
rules are simply incorrect and we need to figure out what to do about it. It
seems that the best thing to do would be to fully expalnd the subtheories
(so that we get cases for all the rules, including the ones from
subtheories), but this approach might have its own downsides.
