group Comparability Concepts

Assortment of concept definitions requiring types to be comparable in various ways.

Example:

using namespace hyperion::mpl::concepts;
struct not_comparable {};

static_assert(EqualityComparable<int, int>);
static_assert(!EqualityComparable<not_comparable, not_comparable>);
