Add Navigators for Sorted Sequences

IGJoshua commented 3 years ago

This PR adds support for three new navigators which all navigate to a sorted version of the current sequence.

SORTED, a parameter-less navigator which navigates to a transformable view of the current sequence as if it were run through sort
sorted, a single-parameter navigator which is the same as SORTED but takes a comparator
sorted-by, a dynamic navigator which takes a keypath for the sort key and an optional comparator
