check_boundaries

There is a boundary (tract 6878, corner 1, boundary 1) in the federal
database
for the 2012 survey that runs exactly through the plot. If that boundary
would be valid, at that corner the term "stand" is not defined.

The German national forest inventory uses angle count sampling,
a sampling method first published as `Bitterlich, W.: Die Winkelzählmessung.
Allgemeine Forst- und Holzwirtschaftliche Zeitung, 58. Jahrg., Folge 11/12
vom Juni 1947` and extended by Grosenbaugh
(<https://academic.oup.com/jof/article-abstract/50/1/32/4684174>)
as probability proportional to size sampling.
When plots are located near stand boundaries, their sizes and hence
their probabilities need to be corrected.
