- complete modification of the creation of AliTPCseed objects from HLT tracks (now method from AliHLTTPCdEdxComponent is used)
- added MC labels on the seeds for comparison between HLT and offline results
- dEdx information present (histogram)

This component is not used in the calibration any more. At the moment it will serve more as a means of comparison with offline. After optimization and correct placement
of the process on the HLT cluster, it can be used for providing the dEdx online.

- testing macro based on AliSimulation producing a TObjArray of AliTPCseed objects per event
