good idea :-)  i'll think more about it and how to implement it within 
the API.

i was referring more to the role of this enum class.  Direction projects 
the concepts of orientation, bipolarity, etc. which really is what is 
meant in this case --i tried to visualise this in the diagrams, 
somewhere in the javadocs.

the more i talk about it, the more i find Direction is more appropriate.

ok.  i'll get rid of them and will checkin the classes soon.


do you have concrete ideas about the Assembly?  if not i'll start on 
this as soon as i checkin the cascade stuff.
