Release Notes: New I/O factories make it possible to build indices on alternative filesystems like HDFS.

Release Notes: Thanks to fastutil 6, MG4J is no longer dependent on COLT. A few bugs have been fixed.
Release Notes: Major improvements were made to indexing. Lightweight compressed-collection construction was added. A skipping system with variable quanta was added. Memory mapping is used for large indices. Many bugs were fixed.
