Add a snippet class for generating the Intercom snippet

[mckenna]

This adds a Snippet class to the Node client, which is exposed through the client like so:

const { Snippet } = require('intercom-client');
const settings = {
  verificationSecret: 'abc123',
  app_id: 'xyz789',
  user_id: 1,
  email: 'peter@intercom.io',
  name: 'Peter McKenna',
  company: {
    id: 123,
    name: 'Intercom'
  }
};
const snippet = new Snippet(settings);
res.send(snippet.create());

It returns the full snippet, including the user_hash.

intercomSettings needs to be an array?

[mckenna]

Doesn't have to be. I figured keeping each key / value pair as an element in an array makes it much easier to join them into a string and not have to worry about where you need to add commas.

JSON.stringify won't work here?

[mckenna]

No, JSON.stringify will quote literally everything (including the braces for the hash), so you'd get this:

const settings = { 
  app_id: 'abc123', 
  name: 'Peter McKenna', 
  user_id: 1 
};

// Returns '{"app_id":"abc123","name":"Peter McKenna","user_id":1}'
JSON.stringify(settings);

It also quotes the key values, which I guess isn't a big deal.

Can we make this snippet work for logged out mode as well?

[mckenna]

Yep! I'll add that.

This supports logged out now.
