setUpPage() is called once on each Test Page before any Test Functions are called.
(setUp() is called before every Test Function)
setUpPage() is especially useful for the asynchronous loading of data documents.
If you implement setUpPage in your Test Page, you need to set the value of a variable called "setUpPageStatus" to "complete" when your function is finished. JsUnit then knows your function is done, and proceeds to execute the page.
