 /**
- * Created by hai on 28/03/16.
+ * An asynchronous implementation of the VotingBoothController.
+ * This implementation binds the other components (storage, ui, output device, and crypto manager),
+ * and runs as its own thread controlling the whole VB process.
+ * The high level details are that it has a queue of commands to handle in order, and a State object which keeps
+ * all data from previous tasks which is necessary for the next task.
+ * It calls executions in the UI and output device asynchronously.
