<p>Rasterize one or multiple polygons. Takes sf or sp polygons as inputs and
returns a list with one <code>RasterLayer</code> per polygon.</p>

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>).
