Class GeohashUtils

Utilities for encoding and decoding geohashes.

This class isn't used by any other part of Spatial4n; it's included largely for convenience of software using Spatial4n. There are other open-source libraries that have more comprehensive geohash utilities but providing this one avoids an additional dependency for what's a small amount of code. If you're using Spatial4n just for this class, consider alternatives.

This code originally came from Apache Lucene, LUCENE-1512.
