* add boolean selector to the MerkleProofGadget, to allow skipping proof verifications when all the slots are not used (eg. in the SignedPod circuit)
* move existing signedpod's circuits draft to its own file
* implement SignedPodVerify circuit
* implement circuit to verify signature (proof-based signature), ie. a 1-level recursion verification
* as agreed in the call, rename Gate -> Gadget when it's not a 'gate'
* make SignatureVerifyGadget conditional on the selector input
* small naming polish
* sigverifygadget: add s computation in-circuit, connect pk,msg,s to internalproof's public_inputs
* optimize signature verify

* Contains should take three arguments (root, key, value)
* Add a test for frontend Dictionaries
* Separate frontend and middleware operations
* Make tests pass: add arg to contains
* Cargo fmt
* Merkleproof verify circuit (#143)
* merkletree: add keypath circuit
* merkletree-circuit: implement proof of existence verification in-circuit
* parametrize max_depth at the tree circuit
* Constrain selectors in-circuit
* implement merketree nonexistence proof circuit, and add edgecase tests
* add non-existence proofs documentation in the mdbook, mv EMPTY->EMPTY_VALUE & NULL->EMPTY_HASH, dependency clean and public exposure methods
* review comments, some extra polishing and add a test that expects wrong proofs to fail
* Add circuit to check only merkleproofs-of-existence
With this, the merkletree_circuit module offers two different circuits:
- `MerkleProofCircuit`: allows to verify both proofs of existence and proofs
non-existence with the same circuit.
- `MerkleProofExistenceCircuit`: allows to verify proofs of existence only.
In this way, if only proofs of existence are needed,
`MerkleProofExistenceCircuit` should be used, which requires less amount
of constraints than `MerkleProofCircuit`.
