/*
        Implementation Summary

        1. Enforce API surface and semantic compatibility with 1.9.x branch
        2. Improve the module's maintainability by reducing the storage
                paths to a single mechanism.
        3. Use the same single mechanism to support "private" and "user" data.
        4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
        5. Avoid exposing implementation details on user objects (eg. expando properties)
        6. Provide a clear path for implementation upgrade to WeakMap in 2014

/*****************************************************************************
* Class name: Vehicle
* Description:
*    A javascript implementation of the IVI vehicle API that communicates
*    to the automotive message broker through a websocket
* Optional constructor arguments:
*    sCB: success callback, called when socket is connected, argument is
*         success message string
*    eCB: error callback, called on socket close or error, argument is error
*         message string
*    url: the URL to use for the websocket, in the form "ws://host:port/script"
*    protocol: the protocol to use for the websocket, default is "http-only"
*
* [Public Member functions]
*  Function name: getSupportedEventTypes(type, writeable, successCB, errorCB)
*    Description:
*        Retrieves a list of vehicle events for the requested type
*    Required arguments:
*        type: target event or group to query (use empty string for all events)
*        writeable: if true, return only writeable events, otherwise get all
*        successCB: success callback, gets called with a string list of names
*              for all the events and event groups that are children of the
*              target. e.g. "vehicle_info" returns all events/groups with the
*              vehicle_info prefix. If the target is an event group, it's
*              omitted from the returned list
*        errorCB: error callback, called with error message string
*
*  Function name: get(eventlist, successCB, errorCB)
*    Description:
*        Retrieves a list of event/value pairs for a target list of event names
*    Required arguments:
*        eventlist[]: list of events to read (use empty string for all events)
*        successCB: success callback, gets called with the event/value pair list
*                   for all requested events. The list is the in the
*                   form of data[n].name/data[n].value
*        errorCB: error callback, called with error message string
*
*  Function name: set(eventlist, valuelist, successCB, errorCB)
*    Description:
*        Sets a gourp of event's values (triggers error on read-only events)
*    Required arguments:
*        eventlist: target events to set
*        valuelist: target event values
*        successCB: success callback, gets called with the eventlist
*                   that was successfully set
*        errorCB: error callback, called with error message string
*
*  Function name: subscribe(eventlist, successCB, errorCB)
*    Description:
*        Subscribe to a list of events so you can listen to value changes, they
*        can be monitored with document.addEventListener(eventname, callback, false);
*        The Event object passed to the callback has two parameters, e.name and
*        e.value. Events are sent to the handler individually.
*    Required arguments:
*        eventlist: target events to listen to
*        successCB: success callback, gets called with the eventlist
*                   that was successfully subscribed
*        errorCB: error callback, called with the eventlist that failed to subscribe
*
*  Function name: unsubscribe(eventlist, successCB, errorCB)
*    Description:
*        Unsubscribe to a list of events to let the server know you're not listening,
*        they should stop being sent from the server if no other clients are using them,
*        but will at least stop being triggered in your app.
*    Required arguments:
*        eventlist: target events to stop listening to
*        successCB: success callback, gets called with the eventlist
*                   that was successfully unsubscribed
*        errorCB: error callback, called with the eventlist that failed to unsubscribe
