Creates a dense multidimensional array containing the arguments.

This macro is used to create an array, similar to the vec! macro for vectors. There are two forms of this macro:

• Create an array containing a given list of elements:

use mdarray::{grid, Grid};

let a = grid![[1, 2], [3, 4]];

assert_eq!(a, Grid::from([[1, 2], [3, 4]]));

• Create an array from a given element and shape by cloning the element:

use mdarray::{grid, Grid};

let a = grid![[1; 2]; 3];

assert_eq!(a, Grid::from_elem([2, 3], 1));

In the second form, like for vectors the shape does not have to be constant.
