Back button should return to prior week
Back button in browser should return you to the week you were looking at. Right now, if you provide a link to students to the calendar, the page always returns to the week of the current date. So, if a student is looking forward or backward a few weeks and clicks on a link, when they hit the back button on the browser, they are no longer looking at the week of interest- instead they are looking at the current date. That is a real hassle.
