Use reveal.js to export the slide deck

Acceptance Criteria

• The task on this issue is to theme a set of slide templates and let people select and export which slides they want to use:
  https://docs.google.com/presentation/d/1zwudnF5g5Egd03freGBSQQSuUvo-eN_k...
• Enable users to select the slides and check them out to be used within reveal.js format.
  Here is a demo: http://revealjs.com/
• Documentation exists as a FAQ page on the Promote Drupal site to outline the steps of exporting their slides with reveal.js and how to open them in a browser to present their slides.

Approach

• We could build our own twig template to override the field template for the entity reference field containing a slide decks referenced nodes. Change the markup to that required by reveal.js and attach the library to the template. Needs confirmation.
• Alternatively we can use https://www.drupal.org/project/revealjs_node → to have this functionality already in place. Needs confirmation.
• At the end create a FAQ on the main site to help people understand how to use the export and take out the slides
