Option to skip certain tests

Hey,

I'm not using dot at all, and my CI system gets this error:

I'm building it using an rpm spec file and this section is failing:

I would recommend, to add graphviz to the RPM dependencies. So dot will be there. As the dotexport is quite famous, it would be good to keep it included.

[jtojnar]

The issue is that graphviz depends on pango, which depends on glib, which depends on gtk-doc, which depends on anytree.

Would it make sense to move anytree exporters into a separate packages?

[c0fec0de]

Will fix it.

Would it make sense to move anytree exporters into a separate packages? That way we can still hhave this tested and break the dependency cycles.

[c0fec0de]

yes. May take a moment.

The idea is to have a anytreelib project, which only includes the anytree core functionality as you need it. anytree will stay as is, as many users make use of the importers and exporters. anytree may then depend on anytreelib. Just not sure if this might frustrate users, as anytree tried to keep the deps to zero (except six).
