    A way to interface with openSCAD which is itself an interface
    to the CGAL CSG bindings.
    CGAL is very stable if difficult to install/use, so this function provides a
    tempfile- happy solution for getting the basic CGAL CSG functionality.

    Parameters
    ---------
    meshes: list of Trimesh objects
    script: string of the script to send to scad.
            Trimesh objects can be referenced in the script as
            $mesh_0, $mesh_1, etc.
