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.
