EventLibrary

Event Library for Robot Framework. This allows one to say that when A happens then do X and when B happens then do Y.

One could argue that there are 3 levels of waiting:

1. Sleeper: Sleep
2. Poller: Wait Until
3. Observer: Invoke When

This library aims to allow you to act with the 3 option.
