```
    Compares two comparable objects. Takes care of null objects. Returns -1, 0 or +1, if o1 less than, equal to or greater than o2. Returns 0 if both objects null, -1 if o1 null but not o2 and +1 if o1 not null but o2.
    
    Parameters:
    
    o1 - the first object
    
    o2 - the second object
    
    Returns:
    
    the comparison result

    m2 - the second map
    
    Returns:
    
    the comparison result
