neighbourselection is only for specifying neighbouring channels.
Neighbouring timepoints and frequencies have a trivial definition and
don'h have to be specified. If you only want clustering in time and
frequency and not over channels, you shoudl specify cfg.neighbours =
{} or [] (I don't know for sure which emnptyit should be right now).
