     * This plugin allows an ES6 module to specify its TypeDoc name.
     * It also allows multiple ES6 modules to be merged together into a single TypeDoc module.
     *
     * @usage
     * At the top of an ES6 module, add a "dynamic module comment".  Insert "@module typedocModuleName" to
     * specify that this ES6 module should be merged with module: "typedocModuleName".
     *
     * Similar to the [[DynamicModulePlugin]], ensure that there is a comment tag (even blank) for the
     * first symbol in the file.
     *
     * @example
     * ```
     *
     * &#47;**
     *  * @module newModuleName
     *  *&#47;
     * &#47;** for typedoc &#47;
     * import {foo} from "../foo";
     * export let bar = "bar";
     * ```
     *
     * Also similar to [[DynamicModulePlugin]], if @preferred is found in a dynamic module comment, the comment
     * will be used as the module comment, and documentation will be generated from it (note: this plugin does not
     * attempt to count lengths of merged module comments in order to guess the best one)
