code: def cross_section(verts, tris, plane_orig, plane_normal, **kwargs):

docs: Compute the planar cross section of a mesh. This returns a set of
      polylines.
  
      Args:
          verts: Nx3 array of the vertices position
          faces: Nx3 array of the faces, containing vertex indices
          plane_orig: 3-vector indicating the plane origin
          plane_normal: 3-vector indicating the plane normal
  
      Returns:
          A list of Nx3 arrays, each representing a disconnected portion
          of the cross section as a polyline
