class RooFormulaVar: public RooAbsReal


 RooRealVar is a generic implementation of a real valued object
 which takes a RooArgList of servers and a C++ expression string defining how
 its value should be calculated from the given list of servers.
 RooRealVar uses a RooFormula object to perform the expression evaluation.

 If RooAbsPdf objects are supplied to RooRealVar as servers, their
 raw (unnormalized) values will be evaluated. Use RooGenericPdf, which
 constructs generic PDF functions, to access their properly normalized
 values.

 The string expression can be any valid TFormula expression referring to the
 listed servers either by name or by their ordinal list position:

   RooRealVar("gen","x*y",RooArgList(x,y))  or
   RooRealVar("gen","@0*@1",RooArgList(x,y))

 The latter form, while slightly less readable, is more versatile because it
 doesn't hardcode any of the variable names it expects
