Enumerates the positions of the grid.

Example

use gridit::PositionsEnumerator;
let grid = Grid::from(vec![1, 2, 1, 2], 2, 2);
let mut iter = grid.iter()
                .grid_positions()
                .filter(|(_, item)| **item == 1);

assert_eq!(iter.next(), Some(((0, 0).into(), &1)));
assert_eq!(iter.next(), Some(((0, 1).into(), &1)));
assert_eq!(iter.next(), None);
