ImmPort/Demo queries

Disease/Alleles
This query takes a while to run.

TBD: Write queries that illustrate the following relationships: (all of these are in the KB)
 * omim-record mentions article. (OMIM)
 * omim-record is-about hpo-class. (HPO)
 * article mentions allele-class. (Medline)
 * omim-record mentions allele-class. (OMIM)
 * mesh-concept mesh-to-chain chain-class. (Alan)
 * article mentions allele-class. (HLA)
 * article is-about allele-class. (HLA)

There is documentation in these places:
 * Bundles/omim
 * Bundles/hpo
 * Bundles/medline/alleles
 * Bundles/hla

Structural features
The following is a bit klunky now; TODO: add a superclass for all structural features to facilitate this sort of query. (see bug 162)

PDB contact points
[Review this one]

Perturbed contact points
(Long-running. This worked before, but is unverified on 2009-11-30)

Contact points
To follow the trail from there to contact points:

(Long running. Review this.  Buggy as of 12/1/09 - no results.)

MaHCO HLA
(Needs review. Maybe use regexp to distinguish serotypes.)

For the following, note that we get articles that we don't get from a Pubmed search for 'A28 A68 HLA'.
