    Hi dev'ils.
    
    While we're at it I'd like to make another change - in BrVertexFilter.
    Currently it works like this:
    
    if (require bb vertex < 15)
    1) check if bb vertex is there
    2) If yes, check if |z|<15 - stop if not
    3) if no bb vertex, continue!
    
    This is good if we then e.g. cut on zdc, but not if bb<15 is my only cut -
    I want to add a flag saying wether you should _demand_ a specific vertex
    (zdc/bb/tpc).
    
    More importantly, I'd like to change the order in which it checks the BB
    vertices - it currently looks for BbRdo first and then for BrBbVertex. I
    guess the other way around would be more sensible since BrBbVertex is more
    precise.
    
    Plus some minor cleanup...
    
    If I don't hear any complaints I'll do this tomorrow.
    
    Ping :-)
