    Represents a Category on a given Site, a subclass of Page. Provides
    additional methods, but Page's own methods should work fine on Category
    objects. Site.get_page() will return a Category instead of a Page if the
    given title is in the category namespace; get_category() is shorthand,
    because it accepts category names without the namespace prefix.
