evelopers can set its
	value in two ways.  First, by setting the <code>val</code> property to have the
	dial jump immediately to that value.  Second, by setting the <code>targVal</code>
	property, the dial will reach the target value based on the set needle rate (<code>needleRate</code>).
	For convenience, the gauge generates an event, <code>onReachTarg</code> when it reaches the target value (only if
	set using <code>targVal</code>).</p>
