-     * mechanism to instrument code for coverage. It uses the `esprima` and
-     * `escodegen` libraries for JS parsing and code generation respectively.
-     *
-     * Works on `node` as well as the browser.
-     *
-     * Usage on nodejs
-     * ---------------
-     *
-     *      var instrumenter = new require('istanbul').Instrumenter(),
-     *          changed = instrumenter.instrumentSync('function meaningOfLife() { return 42; }', 'filename.js');
-     *
-     * Usage in a browser
-     * ------------------
-     *
-     * Load `esprima.js`, `escodegen.js` and `instrumenter.js` (this file) using `script` tags or other means.
-     *
-     * Create an instrumenter object as:
-     *
-     *      var instrumenter = new Instrumenter(),
-     *          changed = instrumenter.instrumentSync('function meaningOfLife() { return 42; }', 'filename.js');
-     *
-     * Aside from demonstration purposes, it is unclear why you would want to instrument code in a browser.
-     *
-     * @class Instrumenter
-     * @constructor
-     * @param {Object} options Optional. Configuration options.
-     * @param {String} [options.coverageVariable] the global variable name to use for
-     *      tracking coverage. Defaults to `__coverage__`
-     * @param {Boolean} [options.embedSource] whether to embed the source code of every
-     *      file as an array in the file coverage object for that file. Defaults to `false`
-     * @param {Boolean} [options.preserveComments] whether comments should be preserved in the output. Defaults to `false`
-     * @param {Boolean} [options.noCompact] emit readable code when set. Defaults to `false`
-     * @param {Boolean} [options.esModules] whether the code to instrument contains uses es
-     *      imports or exports.
-     * @param {Boolean} [options.noAutoWrap] do not automatically wrap the source in
-     *      an anonymous function before covering it. By default, code is wrapped in
-     *      an anonymous function before it is parsed. This is done because
-     *      some nodejs libraries have `return` statements outside of
-     *      a function which is technically invalid Javascript and causes the parser to fail.
-     *      This construct, however, works correctly in node since module loading
-     *      is done in the context of an anonymous function.
-     *
-     * Note that the semantics of the code *returned* by the instrumenter does not change in any way.
-     * The function wrapper is "unwrapped" before the instrumented code is generated.
-     * @param {Object} [options.codeGenerationOptions] an object that is directly passed to the `escodegen`
-     *      library as configuration for code generation. The `noCompact` setting is not honored when this
-     *      option is specified
-     * @param {Boolean} [options.debug] assist in debugging. Currently, the only effect of
-     *      setting this option is a pretty-print of the coverage variable. Defaults to `false`
-     * @param {Boolean} [options.walkDebug] assist in debugging of the AST walker used by this class.
