Form UI updates
- The lunch times are automatically filled in when requested (closing issue #79 (closed))
- Various additions from issue #45 (closed):
- Lunch option selected by default
- Removed window width
- Opening distance explained on the right of app
- Added tooltips to explain the different input sections and this effectively allowed me to reformat the quick guide in the application.
- Minor update to report change R0 to expected number of new cases (closing issue #97 (closed) since this is required by tomorrow)
