Module grid 

Fast 2-dimensional Grid backed by a single vec. This module is designed to work with Point.

The traits Index and IndexMut are implemented for Point to allow usage like:

  let mut grid = Grid::parse("1");
  let point = Point::new(0, 0);

  let foo = grid[point];
  assert_eq!(foo, b'1');

  grid[point] = foo + 1;
  assert_eq!(grid[point], b'2');

A convenience parse method creates a Grid directly from a 2-dimensional set of ASCII characters, a common occurrence in Advent of Code inputs. The same_size_with function creates a grid of the same size that can be used in BFS algorithms for tracking visited locations or for tracking cost in Dijkstra.
