Although I have not much experience with alignments, I would suggest 
that we go for the first option. If programmed cleverly, it should 
allow for expansion to more sophisticated calculations. This expansion 
can be done within BioCocoa, or by the user of the framework.

Could you please explain this in a littile more detail? My 
understanding of alignment calculations is that these are very 
complicated and need a lot of processing power (correct me if I am 
wrong). Therefore we should consider using C directly, without much 
overhead of ObjC classes.
