bellman "Community edition"

Originally developed for ZCash, it has diverged now and focuses solely on the PLONK proof system. Uses our "community edition" pairing for Ethereum's BN256 curve.

Features

Allows one to design PLONK circuits with custom gates and lookup tables with junction with franklin-crypto gadget library. At the moment the lookup argument implies using the lookup over the first three state columns (usually refered as A/B/C) and allows to have simultaneously a gate and a lookup applied on the same row of the trace.
