/**
 * @class AliHLTTPCCASliceOutput
 *
 * AliHLTTPCCASliceOutput class is used to store the output of AliHLTTPCCATracker{Component}
 * and transport the output to AliHLTTPCCAGBMerger{Component}
 *
 * The class contains all the necessary information about TPC tracks, reconstructed in one slice.
 * This includes the reconstructed track parameters and some compressed information
 * about the assigned clusters: clusterId, position and amplitude.
