The principal stresses are now computed as solution of the eigenvalue problem of the stress matrix. This should be faster, more concise and extendable to 3D (but I haven't implemented it yet).
The principal stresses are now computed as average among all the integration points, thus now is valid for triangular and quads elements (or any other...).
The results in rhino are now shown using the correct orientation in 3D.
Two more examples have been added: one showing the calculations in a scripted format; the other showing the results when applied to a 3D (though shells) geometry.
