Build RooPolynomial / RooChebychev Pdf.
/// configStr = Polynomial ["<Optional Title>"] /// configStr = Chebychev ["<Optional Title>"] /// x = AbsReal Def /// nOrder = <orderVal> /// P01 = AbsReal Def /// ... /// P<orderVal> = AbsReal Def
x is the default observable. nOrder is an integer representing the order of the polynomial. P01 ... P<orderVal> define all the coeffs. P00 is not needed. All the AbsReal variables can be RooRealVar or RooFormulaVar.

Initial function called by ctor.
init is called by the ctor. It first creates the parameters by calling createAbsReal, and finally it builds RooPolynomial/RooChebychev PDF with _pdfType being Polynomial/Chebychev, respectively.
Reimplemented from rarBasePdf.
