-// |MapKeyIterator| and |MapValueIterator| are templated interfaces for
-// iterating over a Map<>'s keys and its values, respectively.  They provide a
-// begin() and end() for generating an STL-iterator.  The generated Iterator
-// follows the BidirectionalIterator concept
-// (http://en.cppreference.com/w/cpp/concept/BidirectionalIterator).
-//
-// Example usage:
-//
-//  Map<int,int> my_map;
-//  my_map[1] = 2;
-//  my_map[3] = 4;
-//  my_map[5] = 6;
