Show fusion protein regions in sequence viewer

[Elaine Meng]

From ticket #8283:

Actually, what I would REALLY like even better (or in addition) is if you show the sequence from the structure (command: seq chain /A) it would be able to show you the boundaries on that one sequence. Maybe this info is in the file? I see this and I think the lysozyme residues are numbers 1002-1161 in the structure. Not sure about the other numbers, maybe they are in the uniprot sequence numbering.

_struct_ref_seq.pdbx_auth_seq_align_end
1 1 2RH1 A 8 ? 237 ? P07550 1 ? 230 ? 1 230
2 2 2RH1 A 238 ? 397 ? P00720 2 ? 161 ? 1002 1161
3 3 2RH1 A 398 ? 500 ? P07550 263 ? 365 ? 263 365

I believe this request is already fulfilled sufficiently by the changes made for #8283.  Namely, now that "log chains" shows residue ranges for each UniProt ID and clicking that range selects the residues, it is easy to see the boundaries by way of the selection region in the whole fusion-protein sequence.  The whole sequence can be shown by clicking the description of that chain in the table resulting from  "log chains".  Automatically creating some other region(s) in that sequence might be nice, but would also add complexity to the interface and its options, so my opinion is it is not worth it.  Unless somebody objects I think this ticket could be closed.

I thought what Tom had implemented *might* already be sufficient. Good!
