+     PageHandle is a class that renders the actual page handles and reacts to
+     click events for pagination.
+
+     This class acts in two modes - control or discrete page handle modes. If
+     one of the `is*` flags is `true`, an instance of this class is under
+     control page handle mode. Setting a `pageIndex` to an instance of this
+     class under control mode has no effect and the correct page index will
+     always be inferred from the `is*` flag. Only one of the `is*` flags should
+     be set to `true` at a time. For example, an instance of this class cannot
+     simultaneously be a rewind control and a fast forward control. A `label`
+     and a `title` template or a string are required to be passed to the
+     constuctor under this mode. If a `title` template is provided, it __MUST__
+     accept a parameter `label`. When the `label` is provided to the `title`
+     template function, its result will be used to render the generated anchor's
+     title attribute.
+
+     If all of the `is*` flags is set to `false`, which is the default, an
+     instance of this class will be in discrete page handle mode. An instance
+     under this mode requires the `pageIndex` to be passed from the constructor
+     as an option and it __MUST__ be a 0-based index of the list of page numbers
+     to render. The constuctor will normalize the base to the same base the
+     underlying PageableCollection collection instance uses. A `label` is not
+     required under this mode, which will default to the equivalent 1-based page
+     index calculated from `pageIndex` and the underlying PageableCollection
+     instance. A provided `label` will still be honored however. The `title`
+     parameter is also not required under this mode, in which case the default
+     `title` template will be used. You are encouraged to provide your own
+     `title` template however if you wish to localize the title strings.
+
+     If this page handle represents the current page, an `active` class will be
+     placed on the root list element.
+
+     if this page handle is at the border of the list of pages, a `disabled`
+     class will be placed on the root list element.
+
+     Only page handles that are neither `active` nor `disabled` will respond to
+     click events and triggers pagination.
