Macro NO_CXX_EXCEPTION was removed from code. Method Raise() was replaced by explicit throw statement. Method Standard_Failure::Caught() was replaced by normal C++mechanism of exception transfer. Method Standard_Failure::Caught() is deprecated now. Eliminated empty constructors. Updated samples. Eliminate empty method ChangeValue from NCollection_Map class. Removed not operable methods from NCollection classes.
