Redesigned App Flow

[sethfri]

The app should have a much simpler flow. Users are often weekend partiers and just want to know the van that will take them from Point A to Point B the fastest. As such, the current flow of picking your stop and delivering arrival times should be completely scrapped. The new flow should be:

1. Open the app. The app uses your current location to figure out what stop you're currently at.
2. Choose your destination stop.
3. The app will take the closest vans for Black, Red, and Gold, add their distance to you to the distance to your destination, and simply report back which van the user should get on to get to their destination the fastest, along with the time it will take to get there.

This way, the user doesn't have to worry about calculating anything. This also simplifies and closes #8, as the user would only have the option of setting a reminder for the one reported van.
