I was thinking about that.  An interface can be used to define what a 
class should contain even if it can't be used in any polymorphic sense. 
  I can then make a function templated to accept a class and assume it 
conforms to an interface (maybe a static check?).  Sadly, when I did 
that, the call to the templated member function failed to get linked in. 
  Commenting out the interface use fixed the problem.  Weird...
