mcell_gset_filter_varmean.Rdgnereate/filter gene features from gstat normalized var/mean
mcell_gset_filter_varmean(gstat_id, gset_id, T_vm, force_new = F)the ID of the gstat object to use
if this exists, filter_varmean will restrict hte current genes in the set with genes matching the var mean threshold, if not, it will generate a new gene sets object with one set including all high variance genes
the threshold on normalized var/mean, recommended values are usually around 0.2, but this may vary with the data
