[Bioperl-l] general coordinate transformation in LocatableSeq

[Mark A. Jensen]

Chris and others interested-
Under bug #2689 I've taken a stab add moving in and out of sequence 
coordinate systems in a general way (aa to/from nt, but also say 
repeats to/from mnemonics), under the guise of a subseq() method for 
LocatableSeq. Prob not for this release, but may be helpful for other 
components as things become (even) more generalized in future. This 
subseq also handles frameshifts. Would be grateful for comments (after 
the rush)-
cheers MAJ
