	Returns the parameter V of the point on the parametric curve corresponding to the Point Pnt. The Correspondence between Pnt and the point P(V) on the parametric curve must be coherent with the way of determination of the signed distance between a point and the implicit curve. Tol is the tolerance on the distance between a point and the parametrised curve. LowParameter and HighParameter give the boundaries of the interval in which the parameter certainly lies. These parameters are given to implement a more efficient algorithm. So, it is not necessary to check that the returned value verifies LowParameter <= Value <= HighParameter.
