- add charts of simulation run results to compare against "real" records, but the
  chart seems to have a minor bug in it. I should split that out from the rest of

- A bunch of UI formatting
- added run/pause button
- streamlined some of the sampler logic
- expanded and streamlined event handling for changes to parameters
- made the "continent" always a square
