 * @type jQuery
 * @param Object settings;
 *      firstArrow - Image - Pass in an image to replace default image. Default: (new Image()).src="./images/first.gif"
 *      prevArrow - Image - Pass in an image to replace default image. Default: (new Image()).src="./images/prev.gif"
 *      lastArrow - Image - Pass in an image to replace default image. Default: (new Image()).src="./images/last.gif"
 *      nextArrow - Image - Pass in an image to replace default image. Default: (new Image()).src="./images/next.gif"
 *      rowsPerPage - Number - used to determine the starting rows per page. Default: 5
 *      currPage - Number - This is to determine what the starting current page is. Default: 1
 *      optionsForRows - Array - This is to set the values on the rows per page. Default: [5,10,25,50,100]
 *      ignoreRows - Array - This is to specify which 'tr' rows to ignore. It is recommended that you have those rows be invisible as they will mess with page counts. Default: []
 *      topNav - Boolean - This specifies the desire to have the navigation be a top nav bar
