The Google Collections Library 1.0 (ALPHA) is a suite of new collections and
collection-related goodness for Java 5.0, brought to you by Google.

This library is a natural extension of the Java Collections Framework you
already know and love.

The major new types are:

    * BiMap. A Map that guarantees unique values, and supports an inverse view.
    * Multiset. A Collection that may contain duplicate values like a List, yet
      has order-independent equality like a Set. Often used to represent a
      histogram.
    * Multimap. Similar to Map, but may contain duplicate keys. Has subtypes
      SetMultimap and ListMultimap providing more specific behavior.

There are also more than a dozen collection implementations, mostly of the
interfaces above, but not all. ReferenceMap, for example, is a ConcurrentMap
implementation which easily handles any combination of strong, soft or weak
keys with strong, soft or weak values.

Static utility classes include:

    * Comparators. Natural order, compound, null-friendly, ad-hoc . . .
    * Iterators and Iterables. Element-based equality, cycle, concat,
      partition, filter with predicate, transform with function . . .
    * Lists, Sets and Maps. A plethora of convenient factory methods and much
      more.
    * PrimitiveArrays: "boxing"/"unboxing" of primitive arrays

And there's more:

    * Forwarding collections
    * Constrained collections
    * Implementation helpers like AbstractIterator
