| * Syntactic sugar for invoking a function and expanding an array for arguments. |
| * |
| * Common use case would be to use `Function.prototype.apply`. |
| * |
| * ```js |
| * function f(x, y, z) {} |
| * var args = [1, 2, 3]; |
| * f.apply(null, args); |
| * ``` |
| * |
| * With `spread` this example can be re-written. |
| * |
| * ```js |
| * spread(function(x, y, z) {})([1, 2, 3]); |
| * ``` |
| * |
| * @param {Function} callback |
| * @returns {Function} |
