/**
 * Starts and displays status for Hands Free Activation (HFA).
 *
 * This class operates with Hands Free Activation apps. It comes up during activation
 * requests that occur outside of setup wizard and so provides its own UI.
 * It uses {@link HfaLogic} to perform the actual activation and during the process
 * displays a "performing activation..." dialog.  This will remain up until the user
 * chooses to skip the activation (still happens in the background) or the activation
 * is successful.  Upon failure, the dialog also goes away but a subsequent dialog will
 * ask the user if they would like to try again or cancel.
