This method will test the ISet against another ISet for "equality".
true if the two sets contain the same elements.
In this case, "equality" means that the two sets contain the same elements. The "==" and "!=" operators are not overridden by design. If you wish to check for "equivalent" ISet instances, use
Equals(). If you wish to check to see if two references are actually the same object, use "==" and "!=".
