 * @class AliHLTTPCCAInputSettings
 *
 * Global Cellular Automaton-based HLT tracker for TPC detector
 * The class reconstructs tracks in the whole TPC
 * It calls the AliHLTTPCCATracker slice tracker and constructs
 * the global TPC tracks by merging the slice tracks
 *
 * The tracker is designed stand-alone.
 * It will be integrated to the HLT framework via AliHLTTPCCAInputSettingsComponent interface,
 * and to off-line framework via TPC/AliTPCtrackerCA class
 * The class is under construction.
