    This method returns the relation of argument1 to argument2 given context.
    
    Parameters:
    
    argument1 - a DeLP argument
    
    argument2 - a DeLP argument
    
    context - a defeasible logic program as context
    
    Returns:
    
    - Result.IS_BETTER iff argument1 is better than argument2
    - Result.IS_WORSE iff argument1 is worse than argument2
    - Result.IS_EQUAL iff argument1 and argument2 are in the same equivalence class
    - Result.NOT_COMPARABLE iff argument1 and argument2 are not comparable
