Quantitative Structural Model ('QSM') Treatment for Tree Architecture

Provides a set of tools to manipulate, visualize and compute metrics from quantitative structural model of trees (i.e the so-called 'QSM') . It can be used in various context of forest ecology (i.e biomass estimation) and tree architecture (i.e architectural metrics), see Martin-Ducup et al. (2020) <doi:10.1111/1365-2435.13678>. The package is based on a new S4 class called 'aRchi'.
