Construct a base forward curve with a reference date and a payment offset.

Parameters:

name - The name of this curve.

referenceDate - The reference date for this curve, i.e., the date which defined t=0.

paymentOffsetCode - The maturity of the index modeled by this curve.

paymentDateRollConvention - The date roll convention used for adjusting the payment date.

interpolationMethod - The interpolation method used for the curve.

extrapolationMethod - The extrapolation method used for the curve.

interpolationEntity - The entity interpolated/extrapolated.

discountCurveName - The name of the discount curve associated with this forward curve (e.g. OIS for collateralized forwards).
