## API

### `MetronomeContracts(web3, chain)`

Constructor for the Metronome contracts object.
It shall receive a `web3` instance and an optional `chain` parameter that default to `'mainnet'`.
Other supported chains are: `'classic'`, `'ropsten'` and `'mordor'`.
Numeric chain IDs can also be used.

### `metronomeContracts.{contractName}`

The instance of the Metronome contracts will have a property for each contract: `Auctions`, `AutonomousConverter`, `METToken`, `TokenPorter` and `Validator`.
Each contract is an instance of `web3.eth.Contract`.

### `MetronomeContracts.{chain}.{contractName}`

This is a convenience object containing the `abi`, `address` and the `birthblock` of the contract on the specified chain.
