		/**
		 * Pagination plug-in methods - The style and controls of the pagination can significantly 
		 * impact on how the end user interacts with the data in your table, and DataTables allows 
		 * the addition of pagination controls by extending this object, which can then be enabled
		 * through the <i>sPaginationType</i> initialisation parameter. Each pagination type that
		 * is added is an object (the property name of which is what <i>sPaginationType</i> refers
		 * to) that has two properties, both methods that are used by DataTables to update the
		 * control's state.
		 *   <ul>
		 *     <li>
		 *       fnInit -  Initialisation of the paging controls. Called only during initialisation 
		 *         of the table. It is expected that this function will add the required DOM elements 
		 *         to the page for the paging controls to work. The element pointer 
		 *         'oSettings.aanFeatures.p' array is provided by DataTables to contain the paging 
		 *         controls (note that this is a 2D array to allow for multiple instances of each 
		 *         DataTables DOM element). It is suggested that you add the controls to this element 
		 *         as children
		 *       <ul>
	     *         <li>
	     *           Function input parameters:
	     *           <ul>
		 *             <li>{object} DataTables settings object: see {@link DataTable.models.oSettings}.</li>
		 *             <li>{node} Container into which the pagination controls must be inserted</li>
		 *             <li>{function} Draw callback function - whenever the controls cause a page
		 *               change, this method must be called to redraw the table.</li>
	     *           </ul>
	     *         </li>
		 *         <li>
		 *           Function return:
		 *           <ul>
		 *             <li>No return required</li>
		 *           </ul>
		 *         </il>
		 *       </ul>
		 *     </il>
		 *     <li>
		 *       fnInit -  This function is called whenever the paging status of the table changes and is
		 *         typically used to update classes and/or text of the paging controls to reflex the new 
		 *         status.
		 *       <ul>

		 * Sorting plug-in methods - Sorting in DataTables is based on the detected type of the

		 * provide a pre-formatting method that will help speed up sorting by allowing DataTables
