Usually, example sets do not contain any data but are only views on an example table (for example for sampling or feature selection purposes). It should be possible to create a layered view on the data, hence the name multi-layered data view. ExampleSet implementation should support this view concept.<P><P><DL><DT><B>Version:</B></DT> <DD>$Id: ExampleSet.java,v 1.8 2008/05/09 19:22:42 ingomierswa Exp $</DD><DT><B>Author:</B></DT> <DD>Ingo
