Devlog 07:

I changed the emulator from being on device to remote via Firebase. This allows me to test the app cleanly without lagging my computer. The only problem is I get a limited 30 minutes per month, so I have to use them wisely. I also updated the Point2D function to reject non-finite points. This prevents errors on the future. I also added a class that combines all the other functionality into one. It returns an OptionalDouble, which is useful when you don’t know if you are going to get a result. This new function accepts three LandmarkObservations, Then if the result is valid, it returns the angle degrees between the points. If not, it returns nothing.
