I'd like to sum 2D arrays. Let's create 2 random 2D arrays and
sum them.

static T[][] rndMatrix(T)(T max, in int rows, in int cols)

Few performances nitpick for your example to be fair with
benchmarking againt the test:
1. Random (default) is slower then Xorfish.
2. double is twice larger then int and requires twice more
memory, so it would be twice slower th
