+ * @name eachOf
+ * @static
+ * @memberOf module:Collections
+ * @method
+ * @alias forEachOf
+ * @category Collection
+ * @see [async.each]{@link module:Collections.each}
+ * @param {Array|Iterable|Object} coll - A collection to iterate over.
+ * @param {AsyncFunction} 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.
+ * 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) {
