Overall clean-up in maps.h - Rename some map types: * IntegerMap -> RangeMap * StdMap -> SparseMap * FunctorMap -> FunctorToMap * MapFunctor -> MapToFunctor * ForkWriteMap -> ForkMap * SimpleMap -> WrapMap * SimpleWriteMap -> WrapWriteMap - Remove the read-only ForkMap version. - Rename map-creator functions for the read-write arithmetic and logical maps. - Small fixes and improvements in the code. - Fix the typedefs of RangeMap to work correctly with bool type, too. - Rename template parameters, function parameters, and private members in many classes to be uniform and to avoid parameter names starting with underscore. - Use Key and Value types instead of K and V template parameters in public functions. - Extend the documentation with examples (e.g. for basic arithmetic and logical maps). - Many doc improvements. - Reorder the classes. - StoreBoolMap, BackInserterBoolMap, FrontInserterBoolMap, InserterBoolMap, FillBoolMap, SettingOrderBoolMap are almost unchanged, since they will be removed. - Also improve maps_test.cc to correctly check every map class, every constructor, and every creator function.
