About PQ Mesh, conjugate curvature network

Hi Albert,

For making the quads of a mesh planar, there are some examples using kangaroo here:

It usually makes sense to build an initial coarse quad grid manually (informed by the curvature field), then subdivide it before planarization.

The latest Kangaroo release also includes components for generating circular, isothermic, and conical meshes, and for generating the panel offsets and beam layout.
