Every version with its generation: how many principal derivations
lie between it and the root. A version whose parent the edition does
not hold counts as a root. In a stemma that loops, the loop is walked
once round, as lineageOf walks it, so that the stemma of an edition
in that state can still be drawn and repaired.
