-/**\r
- * Class ImporterTopLevel\r
- * \r
- * This class defines a ScriptableObject that can be instantiated \r
- * as a top-level ("global") object to provide functionality similar\r
- * to Java's "import" statement.\r
- * <p>\r
- * This class can be used to create a top-level scope using the following code: \r
- * <pre>\r
- * Scriptable scope = new ImporterTopLevel(cx);\r
- * </pre>\r
- * Then JavaScript code will have access to the following methods:\r
- * <ul>\r
- * <li>importClass - will "import" a class by making its unqualified name \r
- * available as a property of the top-level scope\r
- * <li>importPackage - will "import" all the classes of the package by \r
- * searching for unqualified names as classes qualified\r
- * by the given package.\r
- * </ul>\r
- * The following code from the shell illustrates this use:\r
- * <pre>\r
- * js> importClass(java.io.File)\r
- * js> f = new File('help.txt')\r
- * help.txt\r
- * js> importPackage(java.util)\r
- * js> v = new Vector()\r
- * []\r
