  Improve the comment
  Add assert.isWeb3Provider
  Use more concise dep pointing
  Don't create whole web3 object in beta tests
  Improve the comment
  Add tests for web3@1.0
  Use zeroEx.getAvailableAddressesAsync instead of web3.eth.getAccounts
  Add web3@1.0 to web3Factory
  Support web3@1.0 providers
  Define web3@1.0 types ;)
  Install web3@1.0.0 as web3_beta
