[standard] Commented unused code snippets are all over the template files we need to make it clean

[fusionx1]

Hi im Paul from Drupal Pilipinas and i really want to contribute to this wonderful project that helps and will help thousands of drupal developer around the world.

Motivation:

As i was doing a cursory check on the some of the files ive noticed that there are lots of code snippets that are not being used, which i think it should be removed if we are not using it, especially inside the twig file. I'm really a strong believer of drupal coding standard big or small we should embrace it.

Solution:

I know those commented code snippets were there for a reason, i recommend to remove it in the template file and put it somewhere probably a seperte file that inventory all the functions and if time comes we can retrieve it from that file.

Heres a format:

snippet 1:

//https://github.com/hechoendrupal/DrupalConsole/blob/master/templates/theme/theme.twig
//line 54 
//hook_theme_suggestions_node_alter

/*$node = $variables['elements']['#node'];

  if ($variables['elements']['#view_mode'] == "full") {

  }*/

@fusionx1: I totally agree on removing commented code. I did remove several of those in past PR.

We are planning to provide a --learning option when executing the project, we may include some of that code similar to examples module, when the project is been executed using passing that option.

You can see test this --learning feature on the generate:controller command:

$ drupal generate:controller --learning
