* Make GlobeRotation and GlobeTranslation work for non-globes and move them to the base module * Move ellipsoid and geodetic classes into the core * Allow more things to take scene graph nodes instead of RenderableGlobes * Move goToGeo and related Lua functions into the core * Move more functions from the pathnavigation namespace into the navigation namespace --------- Co-authored-by: Emma Broman <emma.broman@liu.se>
