16 // Class AliHFEvarManager:
17 // Contains definition of the variables which are filled into the
18 // Correction framework container. The class handles both AliCFContainer and
20 // Defining a new variable which has to be monitored can be done via the
21 // function AddVariable. This function also defines a new dimension for the
22 // particle container and appends it to the list of variables. For a new
23 // track the function NewTrack caches the values to be filled into the
24 // correction framework container. With FillContainer the specified
25 // correction framework container is filled. The VarManager also handles
26 // the filling of the correlation matrices
