+ * This plugin adds an `exportMap` property to @module doclets. Each export map

+ * For example, the code below
+ *
+ *     export {foo as bar};
+ *
+ * would be a map like `{foo: 'bar'}`.
+ *
+ * In the case of an export declaration with a source, the export identifier is
+ * prefixed by the source.  For example, this code
+ *
+ *     export {foo as bar} from 'ol/bam';
+ *
+ * would be a map like `{'ol/bam foo': 'bar'}`.
+ *
+ * If a default export is a literal or object expression, the local name will be
+ * an empty string.  For example
+ *
+ *     export default {foo: 'bar'};
+ *
+ * would be a map like `{'': 'default'}`.
