Given an input curve (inputCurve) and an index of a control vertex (index), attempt to produce an output curve (outputCurve) that interpolates the position of that control point, without changing the parameter domain or the total number of control points in the curve. This will be accomplished (if possible) by reparameterizing the curve to introduce a multiple knot of a specified multiplicity. A multiplicity of -1 will produce a full multiplicity knot (equal to the degree of the curve.)
