/**
* 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}
