Polls
We may remember the feature from VW3, but it is commonly used on threads. A poll lets the content ask many users a question and store/show the results for statistical and other purposes.
In VaultWiki 4, a Poll should be another page type, that functions similarly to a template. You can define multiple questions, choices, etc, with the option of taking arguments to make the poll more context sensitive. The template would define how the questions, choices, and results are formatted.
A poll can then be used and instanced in any number of pages, and it will show results that were generated for that page. A page should be able to have more than 1 poll at once.
It should be possible to view the original poll as well, see the aggregate responses, and see a ranking of pages based on the responses.
It should be possible to generate polls from the Admin Panel. Article quality and other ratings would be examples of this. Some polls like this can be available upon installation. It should be possible to automatically add admin-generated polls to articles with an area setting.
