Finalize core app functionality and features

[bermantanner]

Define what the app will do and its must-have features.

I've typed some logistics we may need to consider into the 1/30 meeting notes document (you should read), which, so far, include:
1. Meeting Up: How will users meet up to get into the Uber/Lyft? If they are close, should they walk to a preferred meeting spot? If further apart, should the app allow them to communicate to coordinate, such as one user driving to another due to better long-term parking? Should we suggest common locations like park-and-ride lots?

2. Privacy: How do we make it easy for users to contact each other outside the app, without making it too easy (displaying public information to everyone would be a bad idea)? Should we implement a basic friending system or a matching system like Tinder? Should we verify users' identity or flight information to prevent related issues?

3. Trip Scope: Should we focus on rides to the airport first, since everyone is heading to the same place? Expansion to from the airport would require handling arrival times and terminal meetups.

4. Luggage System: How should luggage be handled? Should users input how much luggage they’re bringing during the match process, or should this simply be part of their in-app communication?

5. Cost Splitting: Will we need any features for cost-splitting?

6. In-App Communication Implementation: What will be the features needed for the in-app messaging?

7. Future Expansion: When naming the app, should we choose something that reflects its functionality while remaining expandable, so it’s not limited to just San Diego airports if we grow later?
