Summary: Collections # 3: Please refactor the setlike methods

Initial Comment:
Looking at the current layout of the collection methods it seems possible to refactor them for most of the collection classes (exception being the "Relation" class) to the classes "Collection" and "OrderedCollection".

This would simplify the layout of many of the collection classes and also allow to document and explain these methods in the realm of the "Collection" class and its immediate subclasses.

The following terms refer to the methods as defined in "kernel\RexxClasses\CoreClasses.orx".


Setlike methods for class "Collection"
--------------------------------------

Please define the following methods for the "Collection" class.

        single_difference
        single_intersection
        single_subset
        single_union
        single_xor

As a result these methods should be removed from the following classes:

        Directory
        Stem
        Table



Setlike methods for class "OrderedCollection"
---------------------------------------------

Please define the following methods for the "OrderedCollection" class.

        ordered_difference
        ordered_intersection
        ordered_subset
        ordered_union
        ordered_xor

As a result these methods should be removed from the following classes:

        Array
        List
        Queue

This RFE has been examined, and has been determined to be inline with
the goals of the ooRexx language.  This is not a commitment that this
feature will be implemented, but this will remain open until someone in
the ooRexx community chooses to implement the feature.

Any committer who wishes to work on this feature should assign the
feature to themselves when they begin.  Any non-committer who wishes to
work on this should indicate their interest by adding a comment to the
RFE.
