/**
 * Retrieve or display pagination code.
 *
 * The defaults for overwriting are:
 * 'page' - Default is null (int). The current page. This function will
 *      automatically determine the value.
 * 'pages' - Default is null (int). The total number of pages. This function will
 *      automatically determine the value.
 * 'range' - Default is 3 (int). The number of page links to show before and after
 *      the current page.
 * 'gap' - Default is 3 (int). The minimum number of pages before a gap is 
 *      replaced with ellipses (...).
 * 'anchor' - Default is 1 (int). The number of links to always show at beginning
 *      and end of pagination
 * 'before' - Default is '<div class="emm-paginate">' (string). The html or text 
 *      to add before the pagination links.
 * 'after' - Default is '</div>' (string). The html or text to add after the
 *      pagination links.
 * 'next_page' - Default is '__('&raquo;')' (string). The text to use for the 
 *      next page link.
 * 'previous_page' - Default is '__('&laquo')' (string). The text to use for the 
 *      previous page link.
 * 'echo' - Default is 1 (int). To return the code instead of echo'ing, set this
 *      to 0 (zero).
