/// Implementation of AliQACheckerBase for MCH and MTR

/// For the moment we only implement the checking of raw data QA for the tracker
/// by looking at the occupancy at the manu level.
/// We count the number of manus above a given occupancy threshold, and
/// depending on that number, the resulting QA flag is warning, error or fatal.
/// (there's no "info" type in this case).
