 * Given a standard table, inject the DOM with cruft (additional divs + tables) to make the tfoot and thead 'static'.
 * Sad that in 2007 this can't be done with straight CSS, but there you go. 
 *
 * Modelled on jquery.datagrid.js by Matthew Knight - Ajax functionality there is overkill, and it
 * doesn't support footers, so here we are.
