Vegetation Processor class
The VegetationProcessor class is used to process the trees in the scene. It contains the necessary attributes to describe the trees, such as the tree library, the configuration, the output folder, the reference origin coordinates, the height range, and the number of trees without height on the database. It also contains methods to process the trees, wrap the trees with CGAL Alpha Wrapping at execution time, set the tree foliage, process the tree height with the height range set by the user in the config file for trees without height on the database, and write the metrics to save usefull information on the program execution an results.

// Methods
//! Alpha Wrap ref tree
MeshCgal wrap_tree(int lod, const std::string &shape);
void setTreeFoliage(Tree<MeshCgal, K> &tree, const MeshCgal &round,
const MeshCgal &oval, const MeshCgal &cone);
void processTreeHeight(Tree<MeshCgal, K> &tree, double min_height,
double max_height, int &nNoHeight);
void writeMetrics(const std::string &output_folder,
size_t num_faces_terrain, size_t num_faces_vege,
double time);The processTree logic has its own function not only to factorize the code but also to be able to parallize it later with async more easily.
//! Process the tree

//! Use `processTree` for each tree in the library
