This PR adds the
SplineBuilder3D
andSplineEvaluator3D
classes to handle 3D splines. Some 3D spline tests are also added.In its current state, Hermite boundary conditions are not handled. Also, the API for the SplineBuilder3D will certainly need to be modified (we currently take as arguments the derivatives on the faces and the cross derivatives on the corners, but we might also want the cross derivatives on the edges).
