 *     This package contains the following immutable set implementations:
 * <ul>
 *     <li>
 *          {@link com.gs.collections.impl.set.immutable.ImmutableEmptySet} - an immutable set with 0 elements.
 *     </li>
 *     <li>
 *          {@link com.gs.collections.impl.set.immutable.ImmutableSingletonSet} - an immutable set with 1 element.
 *     </li>
 *     <li>
 *          {@link com.gs.collections.impl.set.immutable.ImmutableDoubletonSet} - an immutable set with 2 elements.
 *     </li>
 *     <li>
 *          {@link com.gs.collections.impl.set.immutable.ImmutableTripletonSet} - an immutable set with 3 elements.
 *     </li>
 *     <li>
 *          {@link com.gs.collections.impl.set.immutable.ImmutableQuadrupletonSet} - an immutable set with 4 elements.
 *     </li>
 *     <li>
 *          {@link com.gs.collections.impl.set.immutable.ImmutableUnifiedSet} - the non-modifiable equivalent of {@link com.gs.collections.impl.set.mutable.UnifiedSet}.
 *     </li>
 * </ul>
 * <p>
 *     This package contains one factory implementation:
 * <ul>
 *     <li>
 *          {@link com.gs.collections.impl.set.immutable.ImmutableSetFactoryImpl} - a factory which creates instances of type {@link com.gs.collections.api.set.ImmutableSet}.
