Support remoteStorage

[jsjoeio]

This library is great for building POCs but in the real world, data needs to persist. localStorage isn't sufficient.

I'd like to support saving the streak to a database.

I'm exploring some ideas but one idea is to allow the user to provide a third argument which has two functions - getStreak and updateStreak (or saveStreak). We would call these functions for you. I believe this is an example of inversion of control.

Rather making an assumption of how your database is set up or how you want us to connect to it, instead, we just call your callback for you based on our streak logic.
