Good idea, that will also allow us to start working on the BCSequenceIO 
classes.

Already a few things come to mind:

1. Should we have just one BCSequenceReader class, which takes care of 
all various file formats, or should we subclass for each format? I'm 
not sure yet what the best solution is.

2. Some formats can contain multiple seqeuences (eg fasta). Should we 
return an NSArray of BCSequences only in those cases, or to be more 
consistent for all formats? I suggest the latter.

3. Do we need an additional class that holds the BCSequence plus all 
other info, or should everything go into the BCSequence class?


shoot away :D
