Installed sequelize package and modified package.json to include it in the apps config
Created and edited two files
models/models.js => has basic information of the models configuration and the models it's going to export
models/post.js=>the "post" model with the definition of its table's columns + validation rules

Basic views of the post model as given from SWCM
Created the controller for post and all the methods to implement it's CRUD (index, show, new, crate, edit, update, destroy)
Added to app.js the routes to the new posts/views
Added link to posts (books in my case) to layout.ejs and about.html
