Return all gene ids that are annotated at one or more terms in the
category. If the
universeGeneIds slot of
p has length
greater than zero, then the intersection of the gene ids specified in
that slot and the normal return value is given.
A subclass of
End users should not call this directly. This method gets
hyperGTest. To add support for a new

signature should match a subclass of
HyperGParams-class appropriate for the new
A vector of gene identifiers.
