corridor-class

Given a landscape resistance surface, creates minimum planar graph
(Fall et al. (2007) <doi:10.1007/s10021-007-9038-7>) and grains of connectivity
(Galpern et al. (2012) <doi:10.1111/j.1365-294X.2012.05677.x>) models that can be
used to calculate effective distances for landscape connectivity at multiple scales.
Documentation is provided by several vignettes, and a paper
(Chubaty, Galpern & Doctolero (2020) <doi:10.1111/2041-210X.13350>).
