2020-08-14	(FEAT) Context data slots for known types and conditional type rules, as ↵	Josh Chen	1	-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.
2020-08-05	1. fix intros method. 2. Couple extra lemmas; good small test cases for ↵	Josh Chen	1	-0/+40
	normalization in typechecking/elaboration.
2020-08-03	(FEAT) SIDE_CONDS tactical has additional argument specifying how many ↵	Josh Chen	1	-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.

	. 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.
2020-07-27	Hook elaboration into assumptions mechanism	Josh Chen	1	-40/+42

2020-07-21	1. Bugfix: implicits now properly name schematic variables. Fixes problems ↵	Josh Chen	1	-7/+10
	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.
2020-07-21	1. Type-checking/inference now more principled, and the implementation is ↵	Josh Chen	1	-78/+69
	better. 2. Changed most tactics to context tactics.
2020-07-09	Non-annotated object lambda	Josh Chen	1	-4/+4

2020-07-08	minor	Josh Chen	1	-2/+2

2020-06-01	reorganize and add some material	Josh Chen	1	-3/+3

2020-05-31	transport method	Josh Chen	1	-0/+2

2020-05-29	clean up Eckmann-Hilton and move to Identity	Josh Chen	1	-0/+181

2020-05-27	minor	Josh Chen	1	-0/+1

2020-05-27	Eckmann-Hilton, first pass	Josh Chen	1	-0/+16

2020-05-26	new material	Josh Chen	1	-23/+5

2020-05-25	Lists + more reorganizing	Josh Chen	1	-2/+2

2020-05-25	Reorganize theory structure. In particular, the identity type moves out from ↵	Josh Chen	1	-0/+0
	under Spartan to HoTT. Spartan now only has Pi and Sigma.
2020-05-25	slightly nicer homotopy proofs with calculations	Josh Chen	1	-1/+2

2020-05-25	use existing calculation infrastructure for sym and trans	Josh Chen	1	-12/+3

2020-05-25	1. equality method now uses general elimination tactic. 2. New constant `` ↵	Josh Chen	1	-51/+89
	refers to rhs of equalities.
2020-05-24	new work on elimination tactic	Josh Chen	1	-1/+1

2020-05-22	some tweaks and comments, in preparation for general inductive type elimination	Josh Chen	1	-6/+7

2020-04-02	1. make id function an abbrev. 2. fix reduce method	Josh Chen	1	-1/+1

2020-04-02	Brand-spanking new version using Spartan infrastructure	Josh Chen	1	-0/+433
