This branch implements support of btree indexes instead of .kvi files. Kvi also created, but not used during search/lookup, only for size comparation. Btree allows to make seek calls, while recsplit indexes does not support that query. During initial tests, btree indexes are ~1-3% smaller than recsplit but avg lookup time bigger up to 1.5us (which compensates with ability to fetch next key).
