Add points to a geometry model inline.

You can use add_points! to create a series of points inline.

Both regular points and points with characteristic lengths are supported.

This macro returns a new Vec<PointTag>.

let mut geom = gmsh.create_occ_model("model")?;
let lc = 1e-2;
let rect_pts = add_points![geom,
                          (0., 0., 0.),      // basic point
                          (0.1, 0., 0., lc), // point with a target mesh size
                          (0.1, 0.3, 0., lc),
                          (0., 0.3, 0.)];

for pt in rect_pts.iter() {
    println!("{:?}", pt);
}
