Log Message:
Added methods for testing containment of one set in another, and so
on.  These include:

     $A->contains($B)        Test if $B is a subset of $A (or an
                             element of $A if $B$ is a real number).

     $A->isSubsetOf($B)      Test if $A is a subset of $B.

     $A->isEmpty             True if $A is the empty set.

     $A->intersects($B)      True if $A and $B have numbers in common.

     $A->intersect($B)       The set of numbers common to both $A and $B.

Be careful of the difference between "intersect" and "intersects".
One is a set the other a true/false value.
