    public abstract class ResultMatrix

extends java.lang.Object
implements java.io.Serializable, RevisionHandler

This matrix is a container for the datasets and classifier setups and their statistics. Derived classes output the data in different formats. Derived classes need to implement the following methods:

- `toStringMatrix()`
- `toStringKey()`
- `toStringHeader()`
- `toStringSummary()`
- `toStringRanking()`
