示例1: prepareBundleModule

/**
 * Generate code containing import statements to all bundled modules and
 * export statements to re-export their namespaces and exports.
 *
 * Example: a bundle containing files `module-a.js` and `module-b.js` would
 * result in a prepareBundleModule result like:
 *
 *     import * as $moduleA from './module-a.js';
 *     import * as $moduleB from './module-b.js';
 *     import $moduleBDefault from './module-b.js';
 *     export {thing1, thing2} from './module-a.js';
 *     export {thing3} from './module-b.js';
 *     export {$moduleA, $moduleB, $moduleBDefault};
