/*
 * Contrary to appearances, this kind of makes sense, just bear with me for a sec.
 *
 * This is the code we use to breathe life into the otherwise dull and static news thingy.
 * First, we set up whatever we have to set up,
 * Second, we declare newsScrollTo(), which does the necessary calculations and shifts divs,
 * accordingly, centering the view on the the box number n 
 * Third, a number of helper functions that call newsScrollTo() when we click on the 
 * interactive parts of the news thingy (that is, the clickable balls and the
 * arrows)
 * Fourth, juggle_boxes automatically juggles the boxes. 
 *
