[VTP writer] sometimes indices and coordinates are messed up

[modenaxe]

The model is correct, but the visualization is not.

E.g. bug when fibula_r of Rajagopal model is processed

[modenaxe]

User Axel Koussou (not on GitHub) provided a solution:

% Thus, to fix the bug, you just have to add new_points=[]; before the loop : 

    for n = 1:size(points,1) 
        % compute torsion matrix
        TorsRotMat = RotMat(torsion_angle_func_rad(points(n,axis_ind)));
        
        % New points and axis
        new_points(n,:) = (TorsRotMat*points(n,:)')';
        new_normals(n,:) = (TorsRotMat*normals(n,:)')';
    end

working on this on branch v0.3
