Minimal classes to create pages with a hierarchical menu.

Basic building blocks:

cms_menu_node

Node

• base class for a menu item
• Uses a Modified Preorder Tree Traversal as detailed here: http://blogs.sitepoint.com/hierarchical-data-database-2/
• This is not a tree built for high volume changes--saving a node rebuilds the entire tree

cms_page

Page(Node)

• Inherits from Node. Includes an author, page content, etc

PageDirectLink(Node)

• Inherits from node and directly links to an outside page. e.g., a link on the menu goes to a specific url. Created for menu links that go off site.

PageCustomView(Node)

• Inherits from Node. This menu item points to a view name. May not be the best way to do this.
• cms_page/verify_all_page_custom_views.py -> verify_all_page_custom_views()
• This function can be called to make sure that the names specified in the PageCustomView exist in the project's urls.py

Dependencies

• Poor-Man's-Tag, contains one Tag model with 5 attributes
• django-ckeditor, for using the ckeditor with a filebrowser for uploaded files. The dependency may be removed by searching for/removing 'CKEditorWidget'
