How to Implement a Registration Form

This article has been removed because it only explained things that are already explained in other articles. Specifically, to implement a registration form you must:

1. Define a class to represent users;

2. Create a form to ask for the registration information (you can generate this with the make:registration-form command provided by the MakerBundle);

3. Create a controller to process the form;

4. Protect some parts of your application so that only registered users can access to them.
