Neighbourhood API example gets a variable of the wrong type

[MarkRdgOx]

Describe the bug
In the Neighbourhoods section, in section 4, the example defineNeighbourhood function obtains a variable metamodel via:

var timeslotVariable = builder.getSolutionMetaModel().entity(Lesson.class).variable("timeslot", Timeslot.class);

.. and passes it to the constructor of the TimeslotChangeMoveProvider listed in section 3.1.

However, in the actual API, this returns a variable of type VariableMetaModel, rather than the PlanningVariableMetaModel which is required by the TimeslotChangeMoveProvider constructor.

Expected behavior
The example should compile.

Actual behavior
The example fails with a type error.

Additional Information
The correct call appears to be builder.getSolutionMetaModel().genuineEntity(Lesson.class).basicVariable<Timeslot>("timeslot").

Thanks for reporting. Seems that, as the API evolved, not all places in the docs were updated accordingly.
