boost::noncopyable has a private copy constructor and copy assignment 
operator.
This prevents the compiler from generating a copy constructor and 
assignment operator
for derived classes.  That's all noncopyable does.

If you want a clone function, the easiest way is probably to implement a 
private
copy constructor and have clone call it.
