determineType()

char Voxel::determineType(std::array<double,3> vxl_pos, const double& grid_size, const double max_depth, const AtomTree& atomtree);

This method of the Voxel class calls the type assignment routine. Afterwards, it checks whether the voxel type is mixed. If so, the voxel is split into eigth subvoxels. Finally, the voxel type is returned.
