vb_accumulator

Dynamic Positive and Universal accumulators according to the paper: Dynamic Universal Accumulator with Batch Update over Bilinear Groups Provides a dynamic positive accumulator [PositiveAccumulator], that supports membership proofs Provides a dynamic universal accumulator [UniversalAccumulator], that supports membership and non-membership proofs. Both accumulators implement that trait [Accumulator] that contains the common functionality. Allows single and batch additions to the accumulator Both [MembershipWitness] and [NonMembershipWitness] can be updated either using secret key or using public info published by accumulator manager called [Omega]. Most of the update logic is in the trait [Witness] which is implemented by both [MembershipWitness] and [NonMembershipWitness]. Allows single and batch updates to the witness. Provides a zero knowledge proof of membership and non-membership in the accumulators with [ProofProtocol]. The implementation tries to use the same variable names as the paper and thus violate Rust's naming conventions at places.
