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