When an update is received from the server, the following sequence of events occurs:

Response is processed by RemoteClient._processSyncResponse(e).
It creates a EchoRemoteClient.ServerMessage, and adds itself as a completion listener.

ServerMessage.process is invoked, which does the following:

    * Processes libs directives
    * Invokes ServerMessage._processPostLibraryLoad()
          o for each 'dir' directive, calls the appropriate directive processor (see below for how each one works).

EchoRemoteClient.ComponentSyncUpdateProcessor.process(dirElement)

For each child of the dirElement:

    * 'fr' = _processFullRefresh() (means a full page refresh is required)
    * 'ss' = _processStyleSheet() (proceses changes to stylesheets)
    * 'up' = _processUpdate() (processes a component update, such as add or remove a component)
    * 'sp' = _processStoreProperties() (processes a property update, such as changing the text on a label)

_processUpdate()

    * Find the parent element being updated from the up element.
    * If adding a child:
          o Load the component by calling EchoSerial.loadComponent
          o call parentComponent.add(component, cursorIndex)
      Component.add(component, index)
          o Remove any existing parent from the new child
          o Set this as the child's parent
          o Register the application on the child
          o call application.notifyComponentUpdate() for the children of this component
      Application.notifyComponentUpdate
          o Notify any update listeners
          o call EchoApp.Update.Manager._processComponentUpdate
      EchoApp.Update.Manager._processComponentUpdate
          o call this._processComponentAdd(parent, newValue);
