- add batch multiple feature smart contract
- add its interface
- update 0x interface to inherit batch multiple methods
- add sample batch multiplex validator contract

- create new /examples folder
- move BatchMultiplesValidator.sol to /examples

- use private method instead of copy constant

- added missing overrides
- added missing parenthesis

- update scripts to include new contracts
- deploy new contracts in tests/utils/DeployZeroEx.sol
- update artifacts.ts and wrappers.ts files

remove input in BatchMultiplexFeature constructor in DeployZeroEx.sol

- pass encoded calls instead of calls array as validate(...args) first input

- assert meta transaction can be executed with batchMultiplex
- assert onlySelf, onlyOwner modifiers not overruled by batchMultiples

- move revert transaction failed without error in if statement

- removed solved comments
- added payable modifier to feature methods
- added refundsAttachedEth, doesNotReduceEthBalance, onlyDelegateCall modifiers to methods
- added new guard flag in reentrancy guard dep

- refund the minimum between eth attached and the eth left in the proxy net of eth stuck in the proxy before the transaction

- add test file
- update setup pipeline

- merge two batchMultiplex methods
- name differently the 2 implemented methods to prevent console warning in tests and easier testing integration, using `batchMultiplex` and `batchMultiplexOptionalParams`
- remove validate deploy and immutable, as moved in foundry test
- use Contract.selector instead of hashing selector in migrate
- use _revertWithData from ZeroEx.sol to allow decoding expected error
- update interface
- minor linting

- swap zrx and dai with native fill RFQ order and multiplex sell token for token to uniswap through `batchMultiplex`method

- handle edge cases of ETH transfers
- added internal methods for routing
- prevent weth stuck if behavior is STOP
- blacklist non-supported methods
- store implementations of methods that require special handling
- reserve 2 EP storage slots for batch multiplex stoage
- update ci pipeline

- create private method _dispatch to handle execution in both external batch execute methods
- remove unnecessary variable definitions
- remove eventual weth balance in both methods

- removed mapping of selector to implementations from feature storage
- store mapping of selectors that require routing
- storage variable name shortening
- retrieve address of target implementations from proxy storage
- revert on more selectors

- define only 1 mapping in storage, use enum instead of bool to define selector status
- update storage initialization
- move duplicate unwrap weth block to private method
- added method for owner to update storage
- added method to query a selector's status
- rename immutable _weth to WETH

- reorder some methods according to flow: external, public, internal, private; write, read (view, pure)

- use delegatecall in transformERC20 if ETH is not the input token
- use non-conditional `value` in .call as the non-ETH calls are re-routed with delegatecall
- comment improvements

- create custom route as method will fail whenever eth is involved and another call using eth is executed
- blacklist other limit orders
- update comments

- add limit order and wrap eth tests
- refactor batch multiplex tests without using non-supported meta transactions

- add new contract with non payable method for executing batch calls to ZeroEx

- renamed batch multiplex calls for better read
- define a type in libs and use in the 2 batch multiplex feature contracts and interfaces
- use same error behavior as pZEIP1 for uniformity
