1. Harry's bug fix for conflicting array indices.
2. Created two new css files, modelviewer.css and instructions.css to fix the bug where the instructions have a different layout than the widget itself and different styles were needed for the  different layouts.
3. Code conditionally gets css styles based on the referring page.  If index.html or page/widget is the referrer, no styles are added - they have their own style sheets.
