function NodeAccessExampleTestCase::testNodeAccessBasic

Test the "private" node access.

• Create 3 users with "access content" and "create article" permissions.
• Each user creates one private and one not private article.
• Run cron to update search index.
• Test that each user can view the other user's non-private article.
• Test that each user cannot view the other user's private article.
• Test that each user finds only appropriate (non-private + own private) in search results.
• Logout.
• Test that anonymous user can't view, edit or delete private content which has author.
• Test that anonymous user can't view, edit or delete private content with anonymous author.
• Create another user with 'view any private content'.
• Test that user 4 can view all content created above.
• Test that user 4 can search for all content created above.
• Test that user 4 cannot edit private content above.
• Create another user with 'edit any private content'
• Test that user 5 can edit private content.
• Test that user 5 can delete private content.
• Test listings of nodes with 'node_access' tag on database search.
