Data.Discrimination.Internal.WordMap

This module suppose a Word64-based array-mapped PATRICIA Trie.

The most significant nybble is isolated by using techniques based on https://www.fpcomplete.com/user/edwardk/revisiting-matrix-multiplication/part-4 but modified to work nybble-by-nybble rather than bit-by-bit.
