textproc/hs-unicode-collation: import hs-unicode-collation-0.1.3.1

This library provides a pure Haskell implementation of the Unicode
Collation Algorithm described at http://www.unicode.org/reports/tr10/. It
is not as fully-featured or as performant as text-icu, but it avoids a
dependency on a large C library. Locale-specific tailorings are also
provided.
