Model class prototype is undefined

Hi. first of all thank you for this awesome library - it’s amazing! 👍

I wanted to add custom method to the model class, but I’m having problems with accessing to ‘prototype’ property - it’s undefined. Just followed manual, the code below is actually copied over from the doc:

var Sequelize = require('sequelize');

db = new Sequelize('test', 'root', '', {
  host: 'localhost',
  dialect: 'mysql'
});

db.authenticate()
    .then(function(err) {
        debug('Connection has been established successfully.');
    })
    .catch(function (err) {
        debug('Unable to connect to the database:', err);
        process.exit();
    });

var User = db.define('user', { firstname: Sequelize.STRING });

// Adding a class level method
User.classLevelMethod = function() {
  return 'foo';
};

// Adding an instance level method
User.prototype.instanceLevelMethod = function() {  // <---- HERE
  return 'bar';
};```

I have no idea WHY it's undefined... :| To me it looks like not up to date manual or some bug.

sequelize: 3.23.6
nodejs: 6.2.2

The docs are for 4.0 - for 3.0, you need to do `User.Instance.prototype
