* SUMMARY: Testing the internal [[Class]] property of user-defined types.
* See ECMA-262 Edition 3 13-Oct-1999, Section 8.6.2 re [[Class]] property.
*
* Same as class-001.js - but testing user-defined types here, not native types.
* Therefore we expect the [[Class]] property to equal 'Object' in each case - 
*
* The getJSClass() function we use is in a utility file, e.g. "shell.js"
