Added the benchmarking project and the initial performance tests for LevelSearch and FTS4 along with setup configs for plain Core Data, Search Kit and RestKit.
Refactored indexing/querying process.
Some refactoring of the FTS4 implementation in the benchmark suite...still a work in progress.
Apparently write batches are not synchronous...ugh.  Ugly hack to fix tests until I figure out a solution.
Switched the query Predicate to an NSCompoundPredicate for both AND and OR cases which resolves the ordering issue.  Tests are green.
Release 0.1.1
