Re: Proposal to move GeoHashUtils to org.apache.sis.index

[Martin Desruisseaux]

Done the following tasks:

 * Replaced (DataStore + AbstractDataStore) by a single DataStore
   abstract class
 * Renamed DataStoreConnection as StorageConnector
 * Renamed GeoHashUtils as GeoHashCoder and moved to the index package
   of sis-storage.
 * Made GeoHashCoder method non-static. Also modified the
   implementation in this process, and upgraded the test case from
   JUnit 3 to JUnit 4.
