class AliRsnMiniMonitor: public TNamed

  This class contains all code which is used to compute any of the values
  which can be of interest within a resonance analysis. Besides the obvious
  invariant mass, it allows to compute other utility values on all possible
  targets, in order to allow a wide spectrum of binning and checks.
  When needed, this object can also define a binning in the variable which
  it is required to compute, which is used for initializing axes of output
  histograms (see AliRsnFunction).
  The value computation requires this object to be passed the object whose
  informations will be used. This object can be of any allowed input type
  (track, pair, event), then this class must inherit from AliRsnTarget.
  Then, when value computation is attempted, a check on target type is done
  and computation is successful only if expected target matches that of the
  passed object.
  In some cases, the value computation can require a support external object,
  which must then be passed to this class. It can be of any type inheriting
  from TObject.
