Basic Documentation:    *Grabs all link to an mp4, flv and mp3 file and makes them popup into a dialog window and play. 
*If a class videoInline has been applied to that link it will embed the video inline on the page
without a popup dialog.
*If an image is inside the link the generated icon will not appear for popups or the image will
be used as a poster frame for the video if the link has the class videoInline
