// You are given a map of arbitrary size represented 
// as a two-dimensional array, and your job is to 
// return the same map, but rotated 180 degrees.

this.run = function(map) {
    var newmap = [];
    for (var i = map.length-1; i >= 0; i--) {
        newmap.push(map[i].reverse());
    }
    return newmap;
