Pure Go implementation of Bob Jenkins' 32-bit lookup3.c hashlittle hash function

Jenkins hashlittle for Go

This package implements the 32-bit hashlittle() hash function from Bob Jenkins' lookup3.c library. See also the Wikipedia article.

It is written for portability and compatibility, not speed, and implements the Go standard library hash.Hash32 interface. Hashlittle is meant to hash short keys, however, and does not work incrementally as the hash itself uses the key length. Hashing "foo" then "bar" would produce different results than hashing "foobar", for that reason attempting to call Write() more than once on an object returned by lookup3.HashLittle() without resetting in-between will raise an error.

This code is hereby placed in the public domain.
