YUI Datatable statistics

Lamplight uses the YAHOO User Interface   a lot, especially datatables.  One of the things they lack, though, are footer statistics - up to now we've generated them on the server.  But to cope with editable datatables, we needed a dynamic version, so here it is on the YUI blog, with links to github for a demo and source.  And they'll be in Lamplight in the next week or two too!
