Please add tutorial scripts

[dsyme]

It would be so great if this library came with tutorial-style docs, like many of the other F# community libraries. At the moment http://fsprojects.github.io/FSharp.Control.Reactive/ looks like "work in progress" because the tutorials aren't there.

I'd like to contribute to this myself too. Ideally each checkin that adds new functionality would also add a sample to the tutorial scripts.

Entering this now because of this twitter thread

Thanks! I would love help on getting docs for this project.
