This pull request is following the discussion on the issue #1127. Additionally, it integrates the change proposed by #1112. The list of change of this pull request: * ✨ Add `Timer::times_finished` method that counts the number of wraps for repeating timers. * ♻️ Refactored `Timer` * 🐛 Fix a bug where 2 successive calls to `Timer::tick` which makes a repeating timer to finish makes `Timer::just_finished` to return `false` where it should return `true`. Minimal failing example: ```rust use bevy::prelude::*; let mut timer: Timer<()> = Timer::from_seconds(1.0, true); timer.tick(1.5); assert!(timer.finished()); assert!(timer.just_finished()); timer.tick(1.5); assert!(timer.finished()); assert!(timer.just_finished()); // <- This fails where it should not ``` * 📚 Add extensive documentation for Timer with doc examples. * ✨ Add a `Stopwatch` struct similar to `Timer` with extensive doc and tests. Even if the type specialization is not retained for bevy, the doc, bugfix and added method are worth salvaging 😅. This is my first PR for bevy, please be kind to me ❤️ .
