/**
 * Support for client code that extends the analysis server by adding new
 * Dart specific completion contributors.
 *
 * Plugins can register Dart specific completion contributor factories.
 * The registered contributor factories will be used to instantiate new
 * contributors to get completions any time a client issues
 * a 'completion.getSuggestions' request.
 *
 * If a plugin wants to add completions, it should implement
 * [DartCompletionContributorFactory] by including code
 * like the following in the plugin's registerExtensions method:
 *
 *     @override
 *     void registerExtensions(RegisterExtension registerExtension) {
 *       ...
 *       registerExtension(
 *           DART_COMPLETION_CONTRIBUTOR_EXTENSION_POINT_ID,
 *           () => new MyDartCompletionContributor());
 *       ...
 *     }
