SimpleObjectQuery: Implementation expects to work with vertices-obtainable bounding regions

[francocipollone]

Summary

#17 introduces SimpleObjectQuery implementation and the implementation for getting the intersected lanes considers the vertices of the bounding region for the computation.

As this approach requires the vertices, a cast to BoundingBox(only BoundingRegion implementation available) is necessary. Future vertices-less BoundingRegion implementations (like sphere) won't fit with the implementation
