Added Some Unit Testing

Need to add a lot more, and also need to learn more about how the app
works maybe?
Tried Adding More Cases/Tests

Still need to figure out more how people implemented features, not sure
how to test things well. All sorts of different errors are occurring!
Removing Unused Code

I added some stuff I realize I wasn't using/doesn't make sense.
Calling a phone works!

Fixed phone calling bug, added a catch so the app doesn't crash if you
try to call an an invalid number
Changed Emergency Number

Began to try to make the emergency number not as hard-coded, not sure
how/where settings is implemented
Merging Testing with Master

Work please.
