Title: Computation of the 'Area Potentially Available' (APA) to Trees

Description: Maps of the 'area potentially available' (APA) of trees is calculated from
  mapped forest stands using the approach from Gspaltl et al. (2012) <doi:10.1093/forestry/cps052>.
  This is done by computing a rasterized version of
  'weighted voronoi diagrams' using a an approximation of the trees competitive
  ability (e.g., crown radius, leaf area) as weight. The main output are 'Raster*'-
  objects from the 'raster' package that are stored together with the raw data in
  apa_list's, the main class of the 'APAtree' package. Aggregation functions are
  provided to calculate stand characteristics based on APA-maps such as relative
  proportions according to APA-size and the neighborhood diversity index NDiv
  (Glatthorn (2021) <doi:10.1016/j.ecolind.2021.108073>).
