This is a small add-on for integrating reactive programming using [RxJava 2](https://github.com/ReactiveX/RxJava) with [Vaadin 8](https://github.com/vaadin/framework). The add-on provides utility methods for creating observables from buttons and other components that generate events and methods for subscribing components to observables. Additionally, there is a data provider for collecting values from observables. The data provider can be used directly to connect observables to e.g. grids and charts. The Github repo (see Source Code link) contains a demo that demonstrates how this add-on can be used to create a simple dashboard app where data from a data source is visualized using various Vaadin UI components (including Vaadin charts). The add-on is inspired by [RxVaadin](https://github.com/hezamu/RxVaadin). However, this add-on uses the new cool features of Vaadin 8, as well as a new version of RxJava.
