#2988:
Class HelpFuction get new static functions that are used in different Map’s classes and possible in other classes.
Branch was adapted to Hive.
New version of class structure for Maps:

1. 3 new variants of maps (RankMap, SuccessMap and ZeroMap) are added.
2. BaseMap class was simplified, some class members were deleted and other were transported to child class, because some of them are not used in all kinds of maps.
3. Functions between base class and child class were divided in other way.
4. Mutation operators were adapted to work with new class structure. Now mutation make less work for ModelNodes than previously.
5. ModelNode and Model symbols were simplified. They should not take into account a map type.
6. Models frequency analyzers were adapted for new variants of maps.
7. EMMAlgorithm class was adapted to new maps
