/**
 * Executes an explicit command.
 *
 * This is the entry point for arbitrary commands that are executed upon reception of certain
 * events that should be executed on the context of this service. The supported commands are:
 * - Check last update time and possibly schedule an update of the data for later.
 *     This is triggered every day, upon reception of the DATE_CHANGED_INTENT_ACTION broadcast.
 * - Update data NOW.
 *     This is normally received upon trigger of the scheduled update.
 * - Handle a finished download.
 *     This executes the actions that must be taken after a file (metadata or dictionary data
 *     has been downloaded (or failed to download).
 * The commands that can be spun an another thread will be executed serially, in order, on
 * a worker thread that is created on demand and terminates after a short while if there isn't
 * any work left to do.
