normalization in typechecking/elaboration.
2020-08-03(FEAT) SIDE_CONDS tactical has additional argument specifying how many ↵Josh Chen2-15/+7
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.

. spartan/core/goals.ML . spartan/core/elaboration.ML . spartan/core/elaborated_statement.ML (FEAT) More context tacticals and search tacticals. . spartan/core/context_tactical.ML (FEAT) Improved subgoal focus. Moves fully elaborated assumptions into the context (MINOR INCOMPATIBILITY). . spartan/core/focus.ML (FIX) Normalize facts in order to be able to resolve properly. . spartan/core/typechecking.ML (MAIN) New definitions. (MAIN) Renamed theories and theorems. (MAIN) Refactor theories to fit new features.

2020-07-211. Bugfix: implicits now properly name schematic variables. Fixes problems ↵Josh Chen2-19/+22
caused by variable name clashes. 2. reduce method now more principled: restricts to repeating on first subgoal. 3. An example declarative proof in Equivalence.thy.
2020-07-211. Type-checking/inference now more principled, and the implementation is ↵Josh Chen5-117/+109
better. 2. Changed most tactics to context tactics.
