/**
* Like `each`, except that it passes the key (or index) as the second argument
* to the iteratee.
*
* @name eachOf
* @static
* @memberOf async
* @alias forEachOf
* @category Collection
* @param {Array|Object} coll - A collection to iterate over.
* @param {Function} iteratee - A function to apply to each
* item in `coll`. The `key` is the item's key, or index in the case of an
* array. The iteratee is passed a `callback(err)` which must be called once it
* has completed. If no error has occurred, the callback should be run without
* arguments or with an explicit `null` argument. Invoked with
* (item, key, callback).
* @param {Function} [callback] - A callback which is called when all
* `iteratee` functions have finished, or an error occurs. Invoked with (err).
* @example
*
* var obj = {dev: "/dev.json", test: "/test.json", prod: "/prod.json"};
* var configs = {};
*
* async.forEachOf(obj, function (value, key, callback) {
* fs.readFile(__dirname + value, "utf8", function (err, data) {
* if (err) return callback(err);
* try {
* configs[key] = JSON.parse(data);
* } catch (e) {
* return callback(e);
* }
* callback();
* });
* }, function (err) {
* if (err) console.error(err.message);
* // configs is now a map of JSON data
* doSomethingWith(configs);
