Class PForDeltaDocIdSet
DocIdSet implementation based on pfor-delta encoding.
This implementation is inspired from LinkedIn's Kamikaze (http://data.linkedin.com/opensource/kamikaze) and Daniel Lemire's JavaFastPFOR (https://github.com/lemire/JavaFastPFOR).
On the contrary to the original PFOR paper, exceptions are encoded with FOR instead of Simple16.
