  var mediciUtils = require('medici-js');
  var medici = mediciUtils.init('contracts/AdExchange.sol', '<contract deployed address>');
  var utils = require('ethereumjs-util');

  var sig = mediciUtils.sign(s0, ['http://localhost:4000'])
  var vrs = utils.fromRpcSig(sig)
  medici.registerAdvertiser("http://localhost:4000", vrs.v, utils.bufferToHex(vrs.r), utils.bufferToHex(vrs.s), {from: p0})

  sig = mediciUtils.sign(s1, ['http://localhost:5000'])
  vrs = utils.fromRpcSig(sig)
  medici.registerAdvertiser("http://localhost:5000", vrs.v, utils.bufferToHex(vrs.r), utils.bufferToHex(vrs.s), {from: p1})

  medici.registerPublisher({from: p2})

  medici.deposit({from: p0, value:100})
  medici.deposit({from: p1, value:100})
