This adds a number of lemmas for simplification of `Bool` and `Prop` terms. It pulls lemmas from Mathlib and adds additional lemmas where confluence or consistency suggested they are needed. It has been tested against Mathlib using some automated test infrastructure. That testing module is not yet included in this PR, but will be included as part of this. Note. There are currently some comments saying the origin of the simp rule. These will be removed prior to merging, but are added to clarify where the rule came from during review. --------- Co-authored-by: Scott Morrison <scott.morrison@gmail.com> |
