From Andrei:

attached the last version, with bug fixes in tracking. Now you can do
lego plots for everything in alice. It does not do extra steps (except
very seldom in ITS in som very thin tubes - 1 extra step to cross). Much
more stable. I temporarly disabled TGeoVolume::CheckGeometry from the
context menu of volumes since it seems to have a bug that I need to fix.
 Much better version in computing distances.
