Calculate edit distances and edit scripts between vectors.

 An implementation of the Wagner–Fischer dynamic programming algorithm to
 find the optimal edit script and cost between two sequences.
 .
 The implementation in this package is specialised to sequences represented
 with "Data.Vector" but is otherwise agnostic to:
 .
 * The type of values in the vectors;
 .
 * The type representing edit operations; and
 .
 * The type representing the cost of operations.
 .
 This package provides a library for the Haskell programming language.
