   4   * Shamelessly ripped off from the phpbb pager
   5   *
   6   * Supported parameters:
   7   * @param data The Pager object containing the information that needs to be displayed 
   8   * @param style Style, one of the following values: 'links', 'list', 'prevonly', 'forwardonly'
   9   * @param separator The character to use as a separator between pages, defaults to an empty space
  10   * @param next Text to be used to the link to the next page in the sequence. If not present, it defaults to
  11   * whatever the current locale has defined for 'next_post'
  12   * @param previous Text to be used to the link to the previous page in the sequence. If not present, it defaults to
  13   * whatever the current locale has defined for 'prev_post'
  14   * @param disablediv Whether not to enclose the pager data in a <div class="pager">...</pager> or not. Defaults to 'false'
  15   * @param anchor Specify the name of an HTML anchor that will be appended to each one of the links in pages, so that
  16   * we can get the browser to jump to the right section of the page (in case the paged content doesn't start at the
  17   * top of the page)
