* (FEAT) SIDE_CONDS tactical has additional argument specifying how many ↵Josh Chen2020-08-035-23/+35
| | | | | | | | initial subgoals to skip applying the side condition solver to. (FEAT) `intro`, `intros` methods for "logical introduction rules" (as opposed to typechecking `intr` attribute), only works on conclusions with rigid type. (FEAT) CREPEAT_N bounded repetition tactical, used in `intros n` method.
