Type-agnostic directed acyclic graph (DAG), using
@thi.ng/associative
maps & sets as backend.
Implementation based on Stuart Sierra's Clojure version.
- cycle detection
- accessors for direct & transitive dependencies / dependents
- topological sorting
- iterable (in topo order)
STABLE - used in production
