[BBF Standards] Link between basic parts and composite parts

[Deepak Chandran]

Hello Jean,

I think the general agreement is not to have multiple copies of the same 
sequence, which would mean that changing the individual part sequences 
would change the composite parts' sequences.
I believe that the current idea is to represent the sequence of a 
composite part as a sequence of the contained parts; example:

composite part sequence:   pLac, acgg, gfp, taa

where "pLac" and "gfp" are some sort of database IDs for other parts

This is my understanding. I think Raik has implemented something like 
this, so I hope he is able to confirm whether this is similar to the way 
he is representing the sequence.
