[ANN] grid 0.1.0 - A tiny library for two-dimensional arrays

Dear all,

My colleague @K_N managed to have half of the lab addicted to Advent of Code :sweat_smile:

This year, many problems involve grids, and it proved useful to have a tiny library to handle two-dimensional arrays. So here it is (and via opam):

Nothing sophisticated, and nothing you could not do with Array from the standard library, of course, but useful nonetheless.

Note: This is not a linear algebra library.

Happy hacking,
