 another copy of your measure into the current copy. Suppose you were implementing sample mean. 
 The current instance would have a mean mu and sample count m. If buildSingleAverage were invoked 
 on another instance with mean nu and sample count n, you would update the current instance to 
 mean (m*mu+n*nu)/(m+n) and count m+n. This is actually the computation of the micro average.<p>
 
 <p>In some cases the criterion is better if the value returned by <A HREF="../../../../com/rapidminer/tools/math/Averagable.html#getAverage()"><CODE>Averagable.getAverage()</CODE></A> is smaller.
 In order to support optimizations, the method <A HREF="../../../../com/rapidminer/operator/performance/PerformanceCriterion.html#getFitness()"><CODE>PerformanceCriterion.getFitness()</CODE></A> should return the result of 
 <A HREF="../../../../com/rapidminer/tools/math/Averagable.html#getAverage()"><CODE>Averagable.getAverage()</CODE></A> (not from <A HREF="../../../../com/rapidminer/tools/math/Averagable.html#getMikroAverage()"><CODE>Averagable.getMikroAverage()</CODE></A> since the macro average is often more stable
 for this purpose and will be returned by getAverage() if possible) in cases where higher values are better.
 If smaller values are better, the method should return something like -1 * <A HREF="../../../../com/rapidminer/tools/math/Averagable.html#getAverage()"><CODE>Averagable.getAverage()</CODE></A>.</p> 
 
 <p>The methods <A HREF="../../../../com/rapidminer/tools/math/Averagable.html#getName()"><CODE>Averagable.getName()</CODE></A> and <A HREF="../../../../com/rapidminer/operator/performance/PerformanceCriterion.html#getDescription()"><CODE>PerformanceCriterion.getDescription()</CODE></A> are user by the user interface. Please note
 that the name should only contain lowercase letters and underscore (RapidMiner parameter format). You might
 also want to override <A HREF="../../../../com/rapidminer/operator/ResultObjectAdapter.html#toResultString()"><CODE>ResultObjectAdapter.toResultString()</CODE></A> or <A HREF="../../../../com/rapidminer/tools/math/Averagable.html#getVisualizationComponent(com.rapidminer.operator.IOContainer)"><CODE>Averagable.getVisualizationComponent(com.rapidminer.operator.IOContainer)</CODE></A>
 in order to provide a nice visualization for the performance criterion but you usually don't have to.</p>
