A python library to compute the planar cross-section of a 3D mesh.

Given a 3D mesh and a cut plane, this computes a (set of) polyline(s) that
results from cutting the mesh with the plane.

Requires python and numpy. Mayavi is used for visualisation in the examples.

Usage
=====
Run the examples with ::

    python3 examples/0_cross_section.py

Given ::

    In [17]: verts
    Out[17]:
    array([[ 1.6315   , -0.1505   ,  0.       ],
           [ 1.6376   , -0.1516   ,  0.       ],
           [ 1.6493   , -0.1518   ,  0.       ],

       ....:                       plane_normal=(1, 0, 0))
    Out[21]:
    [array([[  1.20000000e+00,  -1.28957692e-01,  -1.02180769e-01],
            [  1.20000000e+00,  -1.37182869e-01,  -8.06541833e-02],
