/**
 * A builder of {@link ConcurrentMap} instances that can have keys or values automatically wrapped
 * in {@linkplain WeakReference weak} references.
 *
 * <p>Usage example:
 *
 * {@snippet :
 * ConcurrentMap<Request, Stopwatch> timers = new MapMaker()

 * immutable <i>supplier</i> of {@code InputStream} instances.
 *
 * <p>{@code ByteSource} provides two kinds of methods:
 *
 * <ul>
 *   <li><b>Methods that return a stream:</b> These methods should return a <i>new</i>, independent
 *       instance each time they are called. The caller is responsible for ensuring that the
 *       returned stream is closed.

 * behavior:
 *
 * {@snippet :
 * BaseEncoding.base16().lowerCase().decode("deadbeef");
 * }
 *
 * <p>Warning: BaseEncoding instances are immutable. Invoking a configuration method has no effect
 * on the receiving instance; you must store and use the new encoding instance it returns, instead.
 *
 * {@snippet :
 * // Do NOT do this
 * BaseEncoding hex = BaseEncoding.base16();
 * hex.lowerCase(); // does nothing!
