* The classes *BOPDS_PassKey* and *BOPDS_PassKeyBoolean* are too excessive and not used any more in Boolean Operations. To replace them the new *BOPDS_Pair* class has been implemented. Thus:
- The method *BOPDS_DS::Interferences()* now returns the *BOPDS_MapOfPair*;
- The method *BOPDS_Iterator::Value()* takes now only two parameters - the indices of interfering sub-shapes.
