class AliTrackFitterKalman: public AliTrackFitter
Kalman-Filter-like fit
to a straight-line crossing a set of arbitrarily oriented planes.
The resulting line is given by the equation:
(x-x0)/vx = (y-y0)/1 = (z-z0)/vz
Parameters of the fit are:
x0,y0,z0 (a point on the line) and
vx,1,vz (a vector collinear with the line)
LIMITATION: The line must not be perpendicular to the Y axis.

Bool_t GetPCA(const AliTrackPoint& p, AliTrackPoint& p2) const
Get the intersection point "i" between the track and the plane the point "p" belongs to.
SetSeed(const Double_t* par, const Double_t* cov)
Set the initial approximation for the track parameters
