class AliRsnListOutput: public TNamed

 Constructor.
 Requires a name for this object (which will be used to name the output object)
 and the definition of the output type from the built-in enumeration.

 Copy constructor.
 Since the pointer objects must be initialized in a second step,
 they are never copied, and then they are initialized to zero.

 Assignment operator.
 Same consideration as the copiy constructor. In this case, there is
 the possibility to have the output objects alreasy initialized, but
 they are anyway reset.

 Destructor.
 Deletes the output objects.

 Clear all output objects. In general, only one will be initialized at a time.

 Adds a value computation object to the list.

 Initializes the output for this object.
 What kind of output depends on the 'fType' data member,
 and in case it is a CF container, also on the 'fSteps'.
 The object is named with the following criterion:
 <prefix>_<name>_<type>_<varList>

 Initialize the 'default' TH1 output object.
 In case one of the expected axes is NULL, the initialization fails.

 Initialize the THnSparse output object.
 In case one of the expected axes is NULL, the initialization fails.

 Initialize the AliCFContainer output object.
 In case one of the expected axes is NULL, the initialization fails.

 Uses the passed argument to compute all values.
 If all computations were successful, fill the output
 Second argument (step) is needed only in case of CF containers.
 Return value is the AND of all computation successes.
