cleared cell constraints everywhere except any width | any height, started adding swell data download

- realized I was using auto layout constraints incorrectly by not trying to get as far as I could using any width | any height
- also realized I can use constraints to bring one label as close as I want to another label dynamically, instead of trying to guess the actual width. one of those things you don't notice until you're already doing it wrong
- added the base of downloading swell data, still need to bring that data into the cell view to replace the placeholder that's there now
