  SigC::slot_class() (class)
  -----------------------
  slot_class() can be applied to a class method to form a Slot with a
  profile equivelent to the method.  At the same time an instance
  of that class must be specified.  This is an unsafe interface.

  This does NOT require that the class be derived from SigC::Object.
  However, the object should be static with regards to the signal system.
  (allocated within the global scope.)  If it is not and a connected
  slot is call it will result in a seg fault.  If the object must
  be destroyed before the connected slots, all connections must
  be disconnected by hand.

  Sample usage:

    struct A
      {
       void foo(int,int);
      } a;

    Slot2<void,int,int> s=slot_class(a,&A::foo);
