B-Janson 38f6da5a85 Add generic systems example (#2636) ... # Objective My attempt at fixing #2142. My very first attempt at contributing to Bevy so more than open to any feedback. I borrowed heavily from the [Bevy Cheatbook page](https://bevy-cheatbook.github.io/patterns/generic-systems.html?highlight=generic#generic-systems). ## Solution Fairly straightforward example using a clean up system to delete entities that are coupled with app state after exiting that state.
