-/**
- * a mechanism to merge multiple coverage objects into one. Handles the use case
- * of overlapping coverage information for the same files in multiple coverage
- * objects and does not double-count in this situation. For example, if
- * you pass the same coverage object multiple times, the final merged object will be
- * no different that any of the objects passed in (except for execution counts).
- *
- * The `Collector` is built for scale to handle thousands of coverage objects.
- * By default, all processing is done in memory since the common use-case is of
- * one or a few coverage objects. You can work around memory
- * issues by passing in a `Store` implementation that stores temporary computations
- * on disk (the `tmp` store, for example).
- *
- * The `getFinalCoverage` method returns an object with merged coverage information
- * and is provided as a convenience for implementors working with coverage information
- * that can fit into memory. Reporters, in the interest of generality, should *not* use this method for
- * creating reports.
- *
- * Usage
- * -----
- *
- *      var collector = new require('istanbul').Collector();
- *
- *      files.forEach(function (f) {
- *          //each coverage object can have overlapping information about multiple files

-/**
- * provides a mechanism to transform code in the scope of `require` or `vm.createScript`.
- * This mechanism is general and relies on a user-supplied `matcher` function that determines when transformations should be
- * performed and a user-supplied `transformer` function that performs the actual transform.
- * Instrumenting code for coverage is one specific example of useful hooking.
- *
- * Note that both the `matcher` and `transformer` must execute synchronously.
- *
- * For the common case of matching filesystem paths based on inclusion/ exclusion patterns, use the `matcherFor`
- * function in the istanbul API to get a matcher.
- *
- * It is up to the transformer to perform processing with side-effects, such as caching, storing the original
- * source code to disk in case of dynamically generated scripts etc. The `Store` class can help you with this.

-     * 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.

-     *      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.

-/**
- * utility methods to process coverage objects. A coverage object has the following
- * format.
- *
- *      {
- *          "/path/to/file1.js": { file1 coverage },
- *          "/path/to/file2.js": { file2 coverage }
- *      }
- *
- *  The internals of the file coverage object are intentionally not documented since
- *  it is not a public interface.
- *
- *  *Note:* When a method of this module has the word `File` in it, it will accept
- *  one of the sub-objects of the main coverage object as an argument. Other
- *  methods accept the higher level coverage object with multiple keys.
- *
- * Works on `node` as well as the browser.
- *
- * Usage on nodejs
- * ---------------
- *
- *      var objectUtils = require('istanbul').utils;
- *
- * Usage in a browser
- * ------------------
- *
- * Load this file using a `script` tag or other means. This will set `window.coverageUtils`
- * to this module's exports.
- *
- * @class ObjectUtils
- * @module main
- * @static
