/**
* This package contains an implementation of a bounded {@link java.util.concurrent.ConcurrentMap} data structure.
*
* {@link Weigher} is a simple interface for determining how many units of capacity an entry consumes. Depending on which concrete Weigher class is
* used, an entry may consume a different amount of space within the cache. The {@link Weighers} class provides utility methods for obtaining the most
* common kinds of implementations.
*
* {@link EvictionListener} provides the ability to be notified when an entry is evicted from the map. An eviction occurs when the entry was
* automatically removed due to the map exceeding a capacity threshold. It is not called when an entry was explicitly removed.
*
* The {@link ConcurrentLinkedHashMap} class supplies an efficient, scalable, thread-safe, bounded map. As with the
* Java Collections Framework the "Concurrent" prefix is used to indicate that the map is not governed by a single exclusion lock.
*
* @see http://code.google.com/p/concurrentlinkedhashmap/
