MVCC 0.0.1

This release includes a function for generating a versioned extractor and a versioned comparator.

A versioned extractor uses the user's key extractor and then creates a compound key by adding the version property from the underlying record object. A versioned comparator first compares the user extracted portion of our versioned key, then compares the version numbers if the extracted keys are equal.

During this iteration I created a pair of iterators that move forward and backward through a versioned Strata b-tree skipping the superseded and disowned versions, but that iterator has been extracted to the project Skip prior to this release.
