Drupal Content types, model entry, tutorial and big report

Drupal has Content types, e.g. Page, Story and blog entry. We can add types and should use that for Model catalogue entries and Tutorials.

• A bonus when using Content types is that the Create content item would add Model catalogue entries and Tutorials as choices of types to create.
• permissions to view, create, edit their own topics and edit all topics of a certain content types can be assigned to user groups.
