Module Ocaml_utils.Diffing_with_keysSource

When diffing lists where each element has a distinct key, we can refine the diffing patch by introducing two composite edit moves: swaps and moves.

Swaps exchange the position of two elements. Swap cost is set to 2 * change - epsilon. Moves change the position of one element. Move cost is set to delete + addition - epsilon.

When the cost delete + addition is greater than change and with those specific weights, the optimal patch with Swaps and Moves can be computed directly and cheaply from the original optimal patch.
