Description: Calculates 3D lacunarity from voxel data. It is designed for use
    with point clouds generated from Light Detection And Ranging (LiDAR) scans
    in order to measure the spatial heterogeneity of 3-dimensional structures
    such as forest stands. It provides fast 'C++' functions to efficiently bin
    point cloud data into voxels and calculate lacunarity using different
    variants of the gliding-box algorithm originated by Allain & Cloitre (1991)
