  Configure background generators 

  Examples for how to use.
  For Fifteen package usage:

    from SourceRate.IBD import dyb_ibd_lso
    ibd_lso =dyb_ibd_lso()

    from Gnrtr.GnrtrConf import Gnrtr
    gnrtrIBDlso = Gnrtr("gnrtrIBDlso");
    gnrtrIBDlso.GenTools = ibd_lso.tools()
    gnrtrIBDlso.ThisStageName = "Kinematic"
    gnrtrIBDlso.TimeStamp = int(wallTime)
    stageCfg.KinematicSequence.Members.append(gnrtrIBDlso)

  For Single usage:

    from SourceRate.IBD import dyb_ibd_lso
    ibd_lso=dyb_ibd_lso()

    import GenTools
    gtc = GenTools.Configure(genname="IBD_lso")
    gtc.generator.TimeStamp = int(wallTime)
    gtc.register(ibd_lso)
