/**
 * This function is used to construct the page lists used throughout the application, e.g. 1 ... 6 7 [8] 9 10 ... 15.
 *
 * - The function accepts a start position, for calculating the page out of the list of possible pages, however if the value is not the start of an actual page, the function will sanitize the value so that it will be the actual start of the 'page' of content. It also will sanitize where the start is beyond the last item.
 * - Many URLs in the application are in the form of item=x.y format, e.g. index.php?topic=1.20 to denote topic 1, 20 items in. This can be achieved by specifying $flexible_start as true, and %1$d in the basic URL component, e.g. passing the base URL as index.php?topic=1.%1$d
 * - Only the first and last pages are linked to, and the display will consist of 5 contiguous items centered on the current page, so displaying the current page and 2 page-links either side)
 *
 * @param string $base_url The basic URL to be used for each link.
 * @param int &$start The start position, by reference. If this is not a multiple of the number of items per page, it is sanitized to be so and the value will persist upon the function's return.
 * @param int $max_value The total number of items you are paginating for.
 * @param int $num_per_page The number of items to be displayed on a given page. $start will be forced to be a multiple of this value.
 * @param bool $flexible_start Whether a ;start=x component should be introduced into the URL automatically (see above)
 * @param bool $show_prevnext Whether the Previous and Next links should be shown (should be on only when navigating the list)
 * @return string The complete HTML of the page index that was requested.
