Feature Vector indexing

Feature Vector indexing (see Schulz 2004) for efficient forward and backward subsumption on Horn Clauses.

This allows to retrieve clauses that (potentially) subsume or are subsumed by a given query clause.

type labels = Index_intf.labels

type feature =

| N of int
| S of ID.Set.t
| M of int ID.Map.t
| L of labels

type feature_vector = feature IArray.t

a vector of feature
