 copy constructor

Double_t GetSeparationGain(const Double_t& nSelS, const Double_t& nSelB, const Double_t& nTotS, const Double_t& nTotB)

 Separation Gain:
 the measure of how the quality of separation of the sample increases
 by splitting the sample e.g. into a "left-node" and a "right-node"
 (N * Index_parent) - (N_left * Index_left) - (N_right * Index_right)
 this is then the quality crition which is optimized for when trying
 to increase the information in the system (making the best selection

virtual ~SeparationBase()

 destructor

{}

Double_t GetSeparationIndex(const Double_t& s, const Double_t& b)

 Return the separation index (a measure for "purity" of the sample")

const TString& GetName()

 Return the name of the concrete Index implementation

{ return fName; }
