* (FEAT) Context data slots for known types and conditional type rules, as ↵Josh Chen2020-08-141-22/+25
| | | | | | | | | | | | | well as a separate one for judgmental equality rules. (REF) Goal statement assumptions are now put into the new context data slots. (FEAT) `assuming` Isar keyword—like `assume` but puts assumptions into context data. (REF) Typechecking and all other tactics refactored to use type information from the context data, as opposed to looking at all facts visible in context. MINOR INCOMPATIBILITY: facts that were implicitly used in proofs now have to be annotated with [type] to make them visible throughout the context, else explicitly passed to methods via `using`, or declared with `assuming`. (REF) Fixed incompatibilities in theories.
* 1. fix intros method. 2. Couple extra lemmas; good small test cases for ↵Josh Chen2020-08-051-0/+40

* (FEAT) SIDE_CONDS tactical has additional argument specifying how many ↵Josh Chen2020-08-031-1/+1
| | | | | | | | 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.

(MAIN) Renamed theories and theorems. (MAIN) Refactor theories to fit new features.

* 1. Bugfix: implicits now properly name schematic variables. Fixes problems ↵Josh Chen2020-07-211-7/+10
