change to single quote strings

[alvaropinot]

nice work dude!

It would be great if the use of single or double quotes strings could be normalized.

IMO, all to single quotes, so we can set a good start point for beginners. Indeed you recommend https://github.com/feross/standard which states the single quote style.

Rules

2 spaces – for indentation
Single quotes for strings – except to avoid escaping

for example from

var firstCat = { name: "bill", lastName: "the cat", address: "The Alley" }

to

var firstCat = { name: 'bill', lastName: 'the cat', address: 'The Alley' }

If you like the idea, I'll be glad to help with the change and make a PR.
