 Remove a kink candidate and references to it from ESD,
 if this candidate does not come from a reconstructed decay
 Not yet implemented...

 Remove a V0 candidate and references to it from ESD,
 if this candidate does not come from a reconstructed decay

 Remove a track and references to it from ESD,
 if this track does not come from a reconstructed decay

 Remove the data which are not needed for the physics analysis.

 1) Cleaning the V0 candidates

    If the cosine of the V0 pointing angle "csp" and
    the DCA between the daughter tracks "dca" does not satisfy
    the conditions

     csp > cleanPars[1] + dca/cleanPars[0]*(1.- cleanPars[1])

    an attempt to remove this V0 candidate from ESD is made.

    The V0 candidate gets removed if it does not belong to any
    recosntructed cascade decay

    12.11.2007, optimal values: cleanPars[0]=0.5, cleanPars[1]=0.999

 2) Cleaning the tracks

    If track's transverse parameter is larger than cleanPars[2]
                       OR
    track's longitudinal parameter is larger than cleanPars[3]
    an attempt to remove this track from ESD is made.

    The track gets removed if it does not come
    from a reconstructed decay
