Back-end: Setup Postgres / Mongo for project

[bonnieli]

• Connect to a database technology on start of your application (please only select one technology, try to choose something that is a good fit for your project if possible, or something you are comfortable with using)
• Create a very basic user model that will be needed for login / signup of the application
• Update the Readme of the application to include some instructions on how to run the application with the db locally

Here are some resources on the technologies:

• Postgres - use SQLAlchemy if you are using Flask/Python and use Sequelize if you are using Node.js/Express
• MongoDB - use Mongoose for Node.js or PyMongo + some object document mapper to make things organized
