+ * The background script forms the core of the addon. Running when the browser starts, it starts the native application
+ * (the intermediary program that connects to the interface). The native application will send it commands in the
+ * format of a JSON object containing a "messageNum" field (containing a session-unique identifier for that message) and
+ * "message" (containing the actual message, of which can be of any type). The message data will be forwarded to several
+ * listeners. The listeners will output a single value (or throw an error). In response to either, the addon will send
+ * a JSON object back to the native application in the following format:
+ *
+ *
+ * {
+ * "messageNum": 0, // The ID of the message that this response corresponds to
+ * "message": { //A wrapper that contains, among other things, the return data
+ * "type": "edu.regis.universeplayer.browserCommands.CommandReturn", // An identifier that tells the interface to treat this data as a return value for a command
+ * "returnValue": null, // The actual data returned by the listeners. In the event of an error, this will be null.
+ * "confirmation": { // Contains extra metadata about how the command was executed
+ * "type": "edu.regis.universeplayer.browserCommands.CommandConfirmation", // Another identifier for the interface
+ * "message": "Done", // A human-readable message on the results of execution. For non-error returns, this will simply be "done."

+ * The default one (registered by this script) does the majority of processing. This default listener takes an object
+ * with a single "type" field that corresponds to an instance of edu.regis.universeplayer.browserCommands.BrowserQuery
+ * in the Java interface. Using that "type" field, it determines what action to take and uses extra data within the
+ * message object. Should the message be something delegated to a foreground tab (i.e. controlling a YouTube video),
+ * the listener will forward the message to the tab in the following format before returning:
+ *
+ *
+ * {
+ * "num": 0, // The ID of the tab-specific message. This is independent of the "messageNum" field above
+ * "message": {} // A copy of the actual message sent.
