Change 2 : Change the used rules to define example and counter example taxon sets.
By default all taxa are example taxa and no counterexample taxa are used.
By using -r option (one or several time) you could restict example taxa to a subset of taxa
In old version all taxa not in example set are in the counterexample set.
Now restrict example set with -r option doesn't define the counter example set.
You must use -i to define the conterexample set in a similar way or -r option for example taxa.
