+/// \brief Converts TracksExtra table from version 000 to 001
+
+/// This task allows for the conversion of the TracksExtra table from version 000 to 001.
+/// The conversion is needed because the table has been extended with the ITSClusterSize column
+/// and the ITSClusterMap column is evaluated dynamically from it.
+/// In the converter a dummy ITSClusterSize column is filled with overflows if a hit in the layer is present
