/*  This is to redirect any URLS with anchors to the proper place.  For instance,
    If you land on a page with #Test in the url, but on which the no element with id="Test"
    exists on the page, then it will be redirected to the "Main_Page" URL.

    That is, if you enter http://www.gabormelli.com/RKB/Fact-oriented_Modeling#Test in the URL bar,
    you should end up on http://www.gabormelli.com/RKB/Main_Page. Likewise, if you enter
    http://www.factmodels.com/SRS1/v080630/#Fact-oriented%20Modeling, you should end up on
