class AliAODRecoDecayLF: public AliAODRecoDecay

 Default Constructor

 Constructor with AliAODVertex for decay vertex

 Constructor with AliAODVertex for decay vertex and without prongs momenta

 Constructor that can used for a "MC" object

 Copy constructor

 assignment operator

 Default Destructor

 Applies the KF vertexer
 Int_t iprongs[nprongs] = indices of the prongs to be used from the vertexer
 Int_t pdgs[nprongs] = pdgs assigned to the prongs, needed to define the AliKFParticle
 Bool_t topoCostraint = if kTRUE, the topological constraint is applied
 Double_t bzkG = magnetic field
 Double_t mass[2] = {mass, sigma} for the mass constraint (if mass[0]>0 the constraint is applied).

 This method returns a primary vertex without the daughter tracks of the
 candidate and it recalculates the impact parameters and errors.

 The output vertex is created with "new". The user has to
 set it to the candidate with SetOwnPrimaryVtx(), unset it at the end
 of processing with UnsetOwnPrimaryVtx() and delete it.
 If a NULL pointer is returned, the removal failed (too few tracks left).

 For the moment, the primary vertex is recalculated from scratch without
 the daughter tracks.

 now recalculate the daughters impact parameters

 Method to smear the impact parameter of the duaghter tracks
 and the sec. vtx position accordinlgy
 Useful to study effect of misalignment.
 The starting point are parameterisations of the impact parameter resolution
 from MC and data
 Errors on d0 and vtx are not recalculated (to be done)

 check if it is like-sign
