[BioC] additional to GOHyperG

Only recently I have posted the problem of not having the corresponding
Affy IDS and Locus IDS to the significant nodes from a GOHyperG
I think this is a problem every body encounters sooner or later when
working with gene ontologies.
I have a temporary solution which performs quite well.
So here is the code:
GOLOCmap: This is the result from applying GOALLLOCUSID to the set of
significant GO IDS. Its a list and every element corresponds to a certain
GO ID and the entries to the LOCUS IDS mapping on it.
LOC: This are the AffyIDS and the corresponding LOCUS IDS, a vector. It
comes from applying hgu133aLOCUSID to a set of AffyIDS.
The function looks for the Locus IDS (LOC) in the entries of every element
of the list GOLOCmap.
The result is a list. Every element corresponds to a certain GO ID and the
entries are the ocurring AffyIDS.
for (i in 1:length(names(GOLOCmap)))
I hope it is useful for some of you. And please let me know if any bugs
