Editable lookup curve for Bevy

Bevy
bevy_lookup_curve π
Editable lookup curve for Bevy that can be used for many things, for example:
- Animation
- Gameplay progressiom (control different aspects over time or other variables)
- Physics (for example: tweakable feel on a character controller)
- Probability control (for item drops etc)
- Shaders
- ... just about anything where you need a formula (x -> y) that you can fine tune, with a GUI instead of diving into math
If you have used AnimationCurve in Unity, this would be an attempt at something similar for Bevy.
Features
- LookupCurve type with modifiable knots and tangents. Three types of interpolation: Constant, Linear, and Cubic
- Asset loader and save functionality
- Egui based editor
- Integration with bevy-inspector-egui for quick and easy tweaking

Using without Bevy
This crate can be used without Bevy as well (except for bevy_math which is a core dependency).
Just set default-features = false. And enable serialize, ron, and/or editor_egui if needed.
See the egui_only example. It can also be used as a standalone curve editor.
