Lists the classification systems registered in the package, one row per
system, in the order classify_all runs them. Each system is a
folder inst/rules/<id>/ holding its key and a system.yaml
entry. The id is what load_rules and
classify_all accept; the aliases are accepted too.
Value
A data.frame with one row per system and the columns
id, name (English display name), edition,
status, classifier (the function that classifies a
PedonRecord in that system), levels and
aliases (both comma-separated), and default (whether
classify_all(systems = "all") runs the system).
