    Currently the steps would be as follows (all from the top of my
    head, so there might be some mistakes): <br>
    - Generate an empty envire::Environment<br>
    - Generate envire::Pointcloud and Frame for it<br>
    - copy base::samples::Pointcloud into envire::Pointcloud (never used
    the base::samples type, so not sure which method to use there)<br>
    - Generate an ElevationGrid and a TraversibilityGrid<br>
    - Generate a Projection operator linking the pointcloud and the
    ElevationGrid<br>
    - Generate a Traversability operator (?)&nbsp; linking the ElevationGrid
    and the TraversabilityGrid<br>
    - run updateAll on the operators<br>
    <br>
