Management interface to be implemented by recorder MBeans.
RecorderMBeans store a value and also keep statistics about the given value.
Different implementations can determine how to acquire and calculate the value.
<p/>
The MBean doesn't starts automatically. It has to wait for a <A HREF="../../../mx4j/tools/stats/StatisticsRecorderMBean.html#start()"><CODE>start()</CODE></A> call
