+    //  Implementation of the InputPolicy used by multi_pass
+    //  split_functor_input gets tokens from a functor
+    // 
+    //  This policy should be used when the functor holds two parts of data: a
+    //  unique part (unique for each instance of the iterator) and a shared 
+    //  part (to be shared between the different copies of the same iterator).
+    //  Using this policy allows to merge the shared part of the functor with 
+    //  the shared part of the iterator data, saving one pointer and one 
+    //  allocation per iterator instance.
+    //
+    //  The Functor template parameter of this policy is expected to be a 
+    //  std::pair<unique, shared>, where 'unique' and 'shared' represent the
+    //  respective parts of the functor itself.
+    //
+    //  Note: the unique part of the functor must have a typedef for result_type
+    //        It also must have a static variable of type result_type defined 
+    //        to represent EOF that is called eof.
