/**
* This package contains implementations of collection and map related key/value classes.
* These are usually used in maps, however they can be used as data holders in any collection.
* <p>
* The following key/value designs are included:
* <ul>
* <li>Map Entry - various map entry implementations
* <li>KeyValue - a key and value pair, without map entry semantics
* <li>MultiKey - a holder of multiple keys tied together
* </ul>
