login-signup:
we created a separate controller to handle sign-up login functionalities by the name of user controller
we used the code present in user.js routes after removing it from user.js under routes
we exported user controller class using an alias in index controller
we removed the schema present in user.js model and imported new user schema present in schema 
we imported user model from models in user.js controller and modified it so that direct routes weren't defined and made
required changes to code keeping rewriting to the minimum.
we added routes in index.js in routes and imported routes in main index file.
