"""
This bot gets a page or list of pages, and checks if it is categorized.
If the page is not a member of any category and has no templates on it, it will
add the {{uncat}} template. Else, if the page is not a member of any category,
but has a template on it, it will check if that template adds the page to a category.
If the template doesn't add the page to a category, again, it will add the {{uncat}}
template to the page.
