	Geom2dLProp_CLProps2d (const Handle< Geom2d_Curve > &C, const Standard_Integer N, const Standard_Real Resolution)
	Initializes the local properties of the curve `The current point and the derivatives are computed at the same time, which allows an optimization of the computation time. <N> indicates the maximum number of derivations to be done (0, 1, 2 or 3). For example, to compute only the tangent, N should be equal to 1. <Resolution> is the linear tolerance (it is used to test if a vector is null).`
