% MSH2Mmeshalongspline(@var{xc}, @var{yc}, @var{Nnx}, @var{Nny},
% @var{sigma})
%
% Generates a structured mesh in a thin layer of size @var{sigma}
% sitting on a natural Catmull-Rom type cubic spline with control
% points @var{xc}, @var{yc}.
% If @var{Nnx} and @var{Nny} are scalars,
% the mesh will have @var{Nnx} nodes in the direction along the
% spline and @var{Nny} in the normal direction.
% If @var{Nnx} and @var{Nny} are vectors they will indicate
% the curvilinear coordinates of the mesh nodes.
% Be aware that if @var{sigma} is not much smaller than the curvature
% of the line the resulting mesh may be invalid.
