// annoyingly many browsers don't have these:
if (!Object.keys) Object.keys = function (obj) {
    var keys = [];
    for (var key in obj) {
        if (obj.hasOwnProperty(key)) {
            keys.push(key);
        }
    }
    return keys;
};

if (!Array.prototype.forEach) Array.prototype.forEach = function (f) {
    for (var i = 0; i < this.length; i++)
        f(this[i]);
};
