simply data app for iPhone and iPad

This app is designed for math teachers who want to make it easier for their students to collect and visualize data.

Heres an overview of how you can use the app:
- As the teacher, you request a session code (a 5 digit number)
- You then provide that code to the class (by whiteboard probably)
- Students then enter that session code and then their data and then press Submit
- The data is stored in the "cloud" so they must be using their data plan or wifi
- As long as students dont delete the session code, they can keep using it to enter more data
- When students click "view data" they will see the data they entered and the data their classmates have entered as well

Important Known Issue: students must press the OK button after they enter the session code and after they enter any data and before they press Submit.
