18/// \class AliMUONTrackerDataWrapper
19///
20/// A simple wrapper to convert an AliMUONVTrackerData object into
21/// an AliMUONVTrackerDataMaker object.
22///
23/// This is mainly to offer backward compatibility : the mchview program
24/// used to save AliMUONVTrackerData objects, while it now saves
25/// AliMUONVTrackerDataMaker ones.
26/// So to read back old files, we need to be able to do the "conversion".
