 *     AliXtAnalysis:
 * This class constructs inclusive and isolated (based on charged tracks)
 * invariant spectra. Isolated case uses a different efficiency where the
 * contamination from cases where non-isolated particle appears as an
 * isolated one due to finite detector efficiency is taken into account.
