Base class to encapsulate a predicate object. Since predicates can be of different types and we do not want to code these types into the template parameter list of the filtered iterator class, we use a base class with an abstract function and templatized derived classes that implement the use of actual predicate types through the virtual function.

Mark the destructor virtual to allow destruction through pointers to the base class.

pure virtual |
Abstract function which in derived classes denotes the evaluation of the predicate on the given iterator.
Implemented in FilteredIterator< BaseIterator >::PredicateTemplate< Predicate >.

Generate a copy of this object, i.e. of the actual type of this pointer.
