// period-> number of cycles between multiplex switches. A value of 0 disables multiplexing for this thread,
// which means you must explicitly call Bgpm_SwitchMux to switch between groups.
// normalize->Pass in BGPM_NORMAL or BGPM_NOTNORMAL to choose whether event counts
// reported by Bgpm_ReadEvent() or Bgpm_ReadEventList() will be scaled to the to the maximum number of cycles spent
// by any mux group.
// With BGPM_NOTNORMAL, Bgpm_ReadEvent() and Bgpm_ReadEventList() report the raw numbers and you may use
// Bgpm_GetMultiplex() and Bgpm_GetMuxEventElapsedCycles() to do your own normalization as desired.
