Installed sequelize
Updated REST API structure documentation
Updated the userController to interact with the ORM rather than using mock data.

Sorted out a basic login request (does not open any session yet) and  the get user request now returns users from the database
Disabled the automatic timestamps sequelize were adding to models (for the time being at least)
Sorted out a typo on a column on the SQL schema.

Also made the note ID auto incrementing
It's now possible to persist notes by posting to /notes/save, see the api structure doc for parameters

Mock data returned from /notes/list are now also built using note models
