02-jun-2005 NvE Bug fix in copy ctor of AliPosition and beginpoint etc... setting of AliTrack.
                In AliTrack all points are now set after first deleting the existing AliPositionObj
                object instead of using the Ali3Vector::Load() memberfunction.
                The bug arose because of the extension of AliPosition with the possibility to
                store an AliTimestamp. This made AliPosition differ from Ali3Vector w.r.t. datamembers.
                Also "cout << endl;" introduced after the Pylist() call in AliCollider in order to
                separate the Pythia event listing from subsequent output due to the mis-interpretation
                of Fortran carriage-control characters on some systems.
