[Biococoa-dev] BCAlignment header added

[Philipp Seibel]

Hi everybody,

i added a simple start for our alignment objects. I think we should 
discuss what everybody thinks a Alignment should be.

Another thing about the BCAnnotations ..

I would suggest a BCAnnotable protocol with

- (void)setAnnotation:(id)aAnnotation forKey:(id)key;
- (id)annotationForKey:(id)key;
- (class)classForKey:(id)key;

this would lead us to a much sleeker structure. I think we will run 
into performance problems, if we have to handle that complex structure 
in every BCSequence object.

and with the protocol everything could be annotable even the Alignment 
or other things as well.

cheers

Phil
