MSH2Mmeshalongspline(xc, yc, Nnx, Nny, sigma)
Generates a structured mesh in a thin layer of size sigma around a natural cubic spline with control points xc, yc. The mesh will have Nnx nodes in the direction along the spline and Nny in the normal direction. Be aware that if sigma is not much smaller than the curvature of the line the resulting mesh may be invalid.
