<DL>
<DD>Sets the attribute with the given index to null. Afterwards, this column
 can be reused. Callers must make sure, that no other example set contains
 a reference to this column. Otherwise its data will be messed up.
 Ususally this is only possible if an operator generates intermediate
 attributes, like a validation chain or a feature generator. If the
 attribute already was removed, this method returns silently.
