Grid::new(usize, usize) panics undocumented

[sadneo]

This doesn't work

use grid::Grid;
fn main() {
    let grid : Grid<u8> = Grid::new(usize::MAX, usize::MAX);
}

while this does

use grid::Grid;
  2 fn main() {
  3     let grid : Grid<u8> = Grid::new(u8::MAX, u8::MAX);
  4 }

Not really sure how the type annotations would look like, but you should probably update the documentation to say that grid lengths can only be sqrt(usize::MAX)

True. It is not possible to have a grid with cols * rows > usize. I will add a note in the docs. Thx
