/**
     * Create a project map (similar to a sitemap) of project.
     *
     * The Reflection component is capable of analyzing one or more files into a hierarchy of objects representing the
     * structure of your project. It does this by analyzing the source code of each individual file using the
     * `analyze()` method in the Analyzer class.
     *
     * Because the Analyzer class requires a whole series of objects that interact together a factory method `create()`
     * is available. This method instantiates all objects and provides a reasonable default to start using the Analyzer.
     *
     * There is also a Service Provider (`\phpDocumentor\Descriptor\ServiceProvider`) that can be used with either Silex
     * or Cilex instead of using the factory method; this will make it easier to plug in your own features if you want to.
