Implement User Seeding Functionality

[alejandrosaenz117]

Creating the first user is complicated and requires multiple steps. This is confusing for first time users.

I suggest creating a seed-user.js file which will automatically create a user. For example:

node seed-user.js

This file will simply need a configuration object that will automatically be passed into the function. This object will include the user's credentials needed to login. Furthermore, this configuration will be thoroughly documented within the seed-user.js file for easy setup.

This task will also update the README with updated instructions.
