Class Description

 RooRealConstant provides static functions to create and keep track
 of RooRealVar constants. Instead of creating such constants by
 hand (e.g. RooRealVar one("one","one",1)), simply use


 whenever a reference to RooRealVar with constant value 1.0 is needed.
 RooRealConstant keeps an internal database of previously created
 RooRealVar objects and will recycle them as appropriate.

RooConstVar& value(Double_t value)
 Lookup existing constant
