* bellman: add VerificationError This adds a distinct VerificationError type to the crate and changes `verify_proof` to return `Result<(), VerificationError>` rather than `Result<bool, SynthesisError>`. This is significantly safer, because it avoids the need to mix pattern-matching logic with boolean logic (the cause of RUSTSEC-2019-0004). * Rename VerificationError variants per review comments. * Add missing Clone impl to VerificationError. |

bellman 
bellman is a crate for building zk-SNARK circuits. It provides circuit traits
and primitive structures, as well as basic gadget implementations such as
booleans and number abstractions.
Roadmap
bellman is being refactored into a generic proving library. Currently it is
pairing-specific, and different types of proving systems need to be implemented
as sub-modules. After the refactor, bellman will be generic using the ff and
group crates, while specific proving systems will be separate crates that pull
in the dependencies they require.
