tessel run fails with TypeError: Cannot read property 'usesContinue' of undefined

[weisjohn]

using this file, climate.js:

```var tessel = require('tessel');
// if you're using a si7020 replace this lib with climate-si7020
var climatelib = require('climate-si7020');

var climate = climatelib.use(tessel.port['C']);


climate.on('ready', function () {
  console.log('Connected to si7005');

  // Loop forever
  setImmediate(function loop () {
    climate.readTemperature('f', function (err, temp) {
      climate.readHumidity(function (err, humid) {
        console.log('Degrees:', temp.toFixed(4) + 'F', 'Humidity:', humid.toFixed(4) + '%RH');
        setTimeout(loop, 300);
      });
    });
  });
});

climate.on('error', function(err) {
  console.log('error connecting module', err);
});

$ tessel run climate.js
