*
* A few notes:
* - this function create a new Object() and assign it as $objname on the global object.
* - every function and variable is placed as a direct property of $objname
* - those functions will have a length of 0. I'd be surprised if someone cares.
* - those functions won't have a prototype. Again, not likely to matter much.
* - variables cannot contain arrays or objects. use the real jsrt:: API for that stuff.
