Bare bones class for 3.5.0 DataTable's recordType = faster render

	// Until some planned performance enhancements are applied to DataTable's infrastructure,
	// this is a quick hack to improve rendering performance if it's needed:

	// Some quacking will be needed for the various places where duck-typing is used
	function DumbRecord(data) {
	this.data = data;
	this._id = 'record_' + DumbRecord._id++;
	this.lists = []; // quack
	}

Keyboard navigable DataTable rows with selection

	/*
	This code should allow users to tab to the first row in the table, which will "select" it by
	adding a class to it and storing a reference to the row node. Alternately, users can click
	on a row to select it. Selection can be shifted to the next or previous row with the up and down arrow keys. The 'enter' key will fire a 'rowAction' custom event.
