* Added Bezier Mesh, a tube around a cubic curve interpolated over 3D points, like a Polyline3D 
* Added Helper classes for shapes generated by a tube around a directrix: knot, curved spring, spring and bezier splines
* Modified all these shapes, so they make use of their helpers.
* Added unidimensionalFunction to evaluate f(x), like torsion or curvature
* DensityFunction now uses generics to deal with any type of map (Point3D for 3D, Double for 1D)

Refactored a few things in SpheroidMesh and Spheroid,
Added quite a few updates to ClothMesh, 
renamed PointLink to Link.
* Added RayTest to detect triangles of a mesh intersected from a ray from a given 3D point. Results are visible through texture coloring
* Added CuboidMesh and a new sample of ray intersection
