made columns border go down the whole length of the viewport
took out CSS transition on analog values. it is too hard to know what time value to use for this. if the server sends updates every 500ms, then we would want to use like 450ms. but then later if we change the server to send updates more often, then we want to reduce the css transition time on the client side, otherwise it will be misleading for the user. this came up in our CCA workshop where the css transition was too long (1 second) and so it was not showing the values from the server fast enough.
