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.
