Promisify everything

Kostas Diakogiannis

AC-2 Promisify the 5 rulers exercise

Rewrite in a promised way the 5 rulers nested callback exercise you did before. Chain all promises together as many times as needed. Stick to 3000ms as a time for the setTimeout for all names this time.

Bonus: If you have done the first part, try to rewrite everything, using again a promise chain, but by no typing the .then() function more than once! Scratch your head on it a bit.
