Class type

Boolean variable on which a DD can branch. Morally just an integer, but kept abstract for safety.

    (*

    closer_to_root v0 v1 says whether, if v0 and v1 were to appear in the same, ordered IDD, v0 or v1 would appear closer to the root.

    *)
val closer_to_root : t -> t -> closer_to_root
val idx_strictly_closer_to_root : Base.int -> Base.int -> Base.bool

idx_strictly_closer_to_root idx0 idx1 is whether a variable with index idx0 is closer to the root of an ordered IDD than a variable with index idx1
