1e10810a1e feat(init/funext): add function extensionality as an axiom. 
This allows us to keep track of theorems which use function extensionality, but not full univalence

5cacebcf86 feat(hott): replace assert by have and merge namespace equiv.ops into equiv 
The coercion A ≃ B -> (A -> B) is now in namespace equiv. The notation ⁻¹ for symmetry of equivalences is not supported anymore. Use ⁻¹ᵉ

e5d5ef9d55 feat(hott/library): various changes and additions. 
Most notably:
Give le.refl the attribute [refl]. This simplifies tactic proofs in various places.
Redefine the order of trunc_index, and instantiate it as weak order.
Add more about pointed equivalences.

5194df5e97 feat(library/local_context): encode order using a tree instead of a list 
Motivations:
- It will be faster to delete local declarations.
- It is faster to find all local declarations that were created after a
give local declaration.
