Rails MVC learning journal.

- Create a controller for students and have it inherit from ApplicationController

- Create a route for the path `/students` that maps to a StudentsController `index` action.

- Add a controller action to the StudentsController named `index`

- Have the new `index` action pull in a list of all of the students with `Student.all` and store it in an instance variable

- Create an `index.html.erb` view file and render it from your `Students#index` action. The `index.html.erb` file should be placed within a `views/students` folder.

- In your view, iterate over the list of students returned from the index action in the controller and display the appropriate information.
