Use R to play sliding puzzle

1	sliding_puzzle(size = c(3, 3), bg = "lightblue", z = NULL)

`size`	two dimensional vector, the size of sliding puzzle. Note: the element of `size` must be greater than 1.
`bg`	the background color of blocks.
`z`	the matrix of sliding puzzle, if z is specified, `size` will be omited.

If size is specified and z is NULL, then the function will generate a solvable sliding puzzle.

Linux/Mac users have to use X11(type = 'Xlib') or the Cairo graphics device Cairo() in the package cairoDevice.

## should use Xlib for the x11() device under *nix, e.g
if (interactive()) {
    if (.Platform$OS.type == "windows") 
        x11() else x11(type = "Xlib")
    sliding_puzzle()
    sliding_puzzle(z = matrix(0:11, 3, 4))
}
