Rhino shell, http://www.mozilla.org/rhino/shell.html , provides "load" 
function that can be used to load external script. You may add a similar 
function to your application that would given an object name load the 
object from external file if it was not already loaded.

You may also have a look at http://www.crockford.com/#javascript about 
various ways to simulate inheritance in JS.
