[Bioperl-l] 'virtual' seqs

[Jason Stajich]

We are processing datafiles - bsml,game, (agave?) documents where it is
possible to just know the length of the sequence but not have any actual
sequence data associated.  I think we should have sequence objects which
can handle this - they would have a length, but seq() would warn and
return undef.  We need one that would implement Bio::Seq::RichSeqI
interface - call it VirtualRichSeq ? Perhaps we'll need the equivalent
PrimaryVirtualSeq and VirtualSeq?

Can someone think of a better name, I don't want to confuse with Ensembl
VirtualXX objects?  This would be implemeted in Bio::Seq:: namespace.
