2022-06-29(broken) update hott for Isabelle 2021-1HEADmasterstuebinm1-6/+6
this just replaces all instance of `this` with instances of `infer`. Unfortunately, it looks likes something else also broke, and I have no idea what it is (but the proof for equiv_if_equal fails). Sadly this means we can't get to univalence for now … (but rn I'm too tired to try anything else with it)

2020-08-14(FEAT) Context data slots for known types and conditional type rules, as ↵Josh Chen1-7/+7
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.
