Hermit

This is used to reparameterize Rational BSpline Curves so that we can concatenate them later to build C1 Curves It builds and 1D-reparameterizing function starting from an Hermite interpolation and adding knots and modifying poles of the 1D BSpline obtained that way. The goal is to build a(u) so that if we consider a BSpline curve N(u) f(u) = ---- D(u).
the function a(u)D(u) has value 1 at the umin and umax and has 0.0e0 derivative value a umin and umax. The details of the computation occurring in this package can be found by reading : " Etude sur la concatenation de NURBS en vue du balayage de surfaces" PFE n S85 Ensam Lille
