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.

This module is a modified version of FeatureVector, with full-signature features that encompass all symbols at the same time.

type labels = Index_intf.labels
type feature =
  1. | N of int
  2. | S of ID.Set.t
  3. | M of int ID.Map.t
  4. | L of labels
type feature_vector = feature IArray.t
