------------------------
o [COLLECTIONS-499] Refactored the test framework for Bag implementations to extend from
"AbstractCollectionTest" by decorating the concrete Bag instance with
a CollectionBag or CollectionSortedBag.
o [COLLECTIONS-498] "CollectionBag" will now also respect the contract of the decorated bag in case
a null argument is provided to either removeAll or retainAll.
o [COLLECTIONS-497] Added bag decorator "CollectionSortedBag" which decorates a SortedBag to make it
comply with the Collection contract.
o [COLLECTIONS-496] "UnmodifiableBoundedCollection" does now also implement the marker interface "Unmodifiable"
similar as all other unmodifiable decorators.
o [COLLECTIONS-495] "UnmodifiableTrie#unmodifiableTrie(Trie)" will not decorate again an already unmodifiable Trie.

o [COLLECTIONS-481] No collision detection/resolution was performed when calling "CompositeSet#addComposited(...)"
with more than one Set as argument. Additionally use varargs parameters instead of arrays
in CompositeSet and CompositeCollection constructor and addComposited method. Thanks to Hollis Waite.
