Defining Map Classes
Every file in every program that uses a map
class must include <Map.h>.
This header file defines three template classes: Map,
Map_pair, and Mapiter.
Each of these templates
takes two type names as arguments representing
the key and value types for a particular
map class. Thus we use Map<int,double> as the class name
of a map with int keys and double values,
Map<String,String> as the class name of a map with
String keys and String values, and so on.
