Uses Teller to login and retrieve details from your bank account

If you want to use this yourself, you'll need the appropriate keys and certs.

I might host this on AWS for learing purposes and ease of access though.

Using it is simple.

1. Log into your bank account (a teller popup should appear for this)
2. Enter your monthly paycheck. This value must be a single numeric value
3. Enter your monthly expenses separated by commas. The app will take care of summing it all up. Example: 20,20,20 will result in 60.
4. Click compute and voila

Note: This app uses whatever currency is used by your bank account, no conversions take place. Keep this in mind if you're feeding the app a different currency as you will have to convert it yourself
