[Bioperl-l] ->alphabet documentation wrong here there and

The documentation is correct we cannot assume that all implementers of the
interface will be mutable.
An interface does not assume that you can set value while a implementation
may choose to allow it. Consider a DBPrimarySeq which is a read-only
representation of the db - it implements the PrimarySeqI interface but
does not allow alphabet to be updated while Bio::PrimarySeq does.
