Issue Description:

Some collections naturally maintain sorted order and can implement `minElement()` and `maxElement()` in O(1). Thus, these algorithms should be protocol requirements to allow collection-specific customizations.

Note that `minElement()` and `maxElement()` that take predicates should continue to be pure extensions.
