325N/A * A special {@link Map} that 'conceptually' stores a set of values for each key.

325N/A * <p>
325N/A * When multiple values are stored, however, this class doesn't let the caller
325N/A * see individual values, and instead it returns a specially designated "MANY" value,
325N/A * which is given as a parameter to the constructor.
