class TQNFBase: public TQNamedTaggable

dummy constructor

 returns a reference to the current list of NF paths
 the actual implementation of this class must keep std::vector<TString> vNFpaths
 updated to contain the full paths where NFs have been deployed.

 set the NF according to the desired scale scheme
 if the tag 'targetPath' is set on this instance, it will be used to deploy the NF
 if this tag is not set, the value of sample path used in the calculation will be used.
@tag:[overwrite] This object tag determines if the NFCalculator's result should overwrite an existing value (1) or if it should be set to the product of the existing and the new value(0). Default: 1 .
@tag:[applyToStopCut] This object tag determines if the NFCalculator's result should be applied to the stopAtCuts. Default: true.

 set the pointer to the info folder
 where information about NFs and their respective processes
 will be stored by the TQNFCalculator

 set the pointer to the cut info folder
 where information about the cut hierarchy is stored
 and can be read by the TQNFCalculator
 the content of the cut info folder will not be modified

 set/change the base sample folder

 set/change the sample data reader

 retrieve the base sample folder

 retrieve the sample data reader

 set the verbosity level
 0 : silent
 1 : some output
 2 : all output

 this function allows to redirect the output of the TFractionFitter
 to an arbitrary file or device on your disk
 including /dev/null in order to dismiss the output irreversibly

 close the output stream assigned to this instance

 returns a list of all individual cuts which are in startCuts or cuts derived
 from these, but not derived from any of stopCuts. The entries in stopCuts are
 inclusive, i.e., these cuts are still added to the returned vector given they
 are derived from one of the start cuts.

if stopCuts is a null pointer no recursion will be performed, instead startCut is simply added to targets.
