Intersection_ ( set S1, list S2 )


Change `S1' so that it becomes the intersection of `S1' and `S2'.
The intersection is the set of those elements that are elements in both sets. So `SetIntersection_' removes (see `SetRemove_') all elements from `S1' that are not in `S2'.
`S2' may be a list that is not a proper set, in which case `Set' is silently applied to it.
