[BioC] How to use datapackage homology

[John Zhang]

>I tried to determine probesets of hgu133a which correspond to transcripts which 
are homologous to all rat transcripts measured on rae230a. I thought using the 
homology datapackage would be a good idea but didn't find any HGIDs in 
rae230aHGID for which entries in homology10116HGID2HGID exist in the released 
datapackages. While trying the development data packages I discovered that the 
rae230aHGID hash is gone in version 1.6.2 of rae230a. 

The developmental track (1.6.2) of homology has a homologyLL2HGID environment 
that maps LocusLink to HGID. The HGID environment has been removed from version 
1.6.2 of the packages for chips because the LOCUSID environment can be used to 
make the link.
