The Hashery is a tight collection of Hash-like classes.

Included among its many offerings are the auto-sorting Dictionary class,
the efficient LRUHash, the flexible OpenHash and the convenient KeyHash.

Nearly every class is a subclass of the CRUDHash which defines a CRUD model
on top of Ruby''s standard Hash making it a snap to subclass and augment
to fit any specific use case.
