/**
* Find all header rows in a thead-less table and put them in a <thead> tag.
* This only treats a row as a header row if it contains only <th>s (no <td>s)
* and if it is preceded entirely by header rows. The algorithm stops when
* it encounters the first non-header row.
*
* After this, it will look at all rows at the bottom for footer rows
* And place these in a tfoot using similar rules.
*
* This function was copied from MediaWiki's jquery.tablesorter module
* @param {jQuery} $table object for a <table>
