Array.sortBy

[El-Dringo-Brannde]

This functionality should be Kindly borrowed from Lodash's _.sortBy

A user should be able to pass in an array of objects and be able to sort them by a value, or a function that returns a truthy value.

Differently from Lodash however, it should keep the original format of whatever data is in the array.

Example:

let users = [
  { 'user': 'fred',   'age': 48 },
  { 'user': 'barney', 'age': 36 },
  { 'user': 'fred',   'age': 40 },
  { 'user': 'barney', 'age': 34 }
];
 
users.sortBy(user => user.user);

console.log(users)
// => objects for [{'barney', 36}, {'barney', 34}, {'fred', 48}, {'fred', 40}]
 
users.sortBy(['user', 'age']);

console.log(users)
// => objects for [{'barney', 34}, {'barney', 36}, {'fred', 40}, {'fred', 48}]

Update README and tests accordingly.

If it's Array.sortBy why pass in the array inside the function as a parameter, shouldn't it be Array.sortBy(funcToBeApplied) or something?

Whoops, too much copy pasta, you're right. I'll update it when I get home.
