Suggest vec![…] instead of wall of vector.push(…) calls

[killercup]

Looking at this code it seems safe to suggest to replace

let mut tris : Vec<Triangle<T, N>> = Vec::new();

tris.push(Triangle::new([p0, p11, p5], 0.));
tris.push(Triangle::new([p0, p5, p1], 0.));
tris.push(Triangle::new([p0, p1, p7], 0.));
tris.push(Triangle::new([p0, p7, p10], 0.));
tris.push(Triangle::new([p0, p10, p11], 0.));

with

let mut tris: Vec<Triangle<T, N>> = vec![
  Triangle::new([p0, p11, p5], 0.),
  Triangle::new([p0, p5, p1], 0.),
  Triangle::new([p0, p1, p7], 0.),
  Triangle::new([p0, p7, p10], 0.),
  Triangle::new([p0, p10, p11], 0.),
];

which has the added bonus of using .with_capacity (IIRC).
