Creates a function that invokes `func` with the `this` binding of the
create function and an array of arguments much like
[`Function#apply`](http://www.ecma-international.org/ecma-262/6.0/#sec-function.prototype.apply).

**Note:** This method is based on the
[spread operator](https://mdn.io/spread_operator).

@param {Function} func The function to spread arguments over.
@param {number} [start=0] The start position of the spread.
@returns {Function} Returns the new function.
@example

var say = _.spread(function(who, what) {
  return who + ' says ' + what;
});

say(['fred', 'hello']);
// => 'fred says hello'

var numbers = Promise.all([
  Promise.resolve(40),
  Promise.resolve(36)
]);

numbers.then(_.spread(function(x, y) {
  return x + y;
}));
// => a Promise of 76
