**embark.logger**
To print messages to the embark log is it better to use ``embark.logger``
instead of ``console``.
e.g ``embark.logger.info("hello")``
**embark.events.on(eventName, callback(*args))**
This call is used to listen and react to events that happen in Embark such as contract deployment
* eventName - name of event to listen to
* available events:
* "contractsDeployed" - triggered when contracts have been deployed
* "file-add", "file-change", "file-remove", "file-event" - triggered on
a file change, args is (filetype, path)
* "abi", "abi-vanila", "abi-contracts-vanila" - triggered when contracts
have been deployed and returns the generated JS code
