Title: Implement only in

# FromElements.In(left).OnlyIn(right)

`OnlyIn` returns elements that are only present in `right`and not in `left`

exemple:

var wrapped = new ListElementsWrapper (new []{ 1, 2, 3 });
var joinList = wrapped.OnlyIn (new List{ 1, 3, 4 });

Check.That (joinList).ContainsExactly (4);
