Bug fix: weather server only worked for western US! If you were in the central or eastern US, you would have gotten a "force close" while downloading weather data the first time (Sorry about that!)
  Now call main weather.gov server, tested at multiple points in US (and outside: should tell you if the weather is not valid now)
Bug noticed (mild, TODO): When starting first time, help is shown. If you rotate the phone during that time it might crash. This doesnt happen during normal usage, just during the first run. Will be fixed in next version
Features to add: Would like a capability where you can click on some future time and find out weather details, and details on why a time might not be good. Maybe some popup or extra summary lines at the bottom?
