public class WekaAttributeRange
extends AbstractDataBackedRange<weka.core.Instances>

Extended Range class that also allows attribute names for specifying attribute positions (names are case-insensitive, just like placeholders for 'first', 'second', etc). If attribute names contain "-" or "," then they need to be surrounded by double-quotes.
