This is a self-contained repository of basic results and utilities for Homotopy Type Theory.
Modules are structured in a hierarchy, where all top-level modules are
imported in this file, and each module only imports and re-exports all
sub-modules. The most basic definitions for a submodule collection are
defined in the core submodule.
For example, in the case of equality, the module called equality is
composed of a number of submodules: core (containing the basic
definitions), groupoid (groupoid laws), calculus (for calculations
involving equality proofs) and reasoning (for equational reasoning).
