From the point of view of bioinformatics, the Strand class is misnamed. Not just because the normal term is 'Chain', but because 'Strand' usually refers to a beta-strand in proteins.
This might seem like a trivial issue, but for purposes of interoperability, and just usability of the cdk for biologists, the name change is important.
I think this makes sense. Please provide a patch.
