Rust eazy to use tweening library
Tweens are created separate from instantiation, which fixes the jump at the start if the tween start does not match the current value.
The trait Lerp describes how a value is interpolated.
If feature glam is enabled, Lerp is available for Vec and Quat (using Slerp)
```rust use std::time::Duration; use ezy::*; let mut val = 0.0;
// Go to 1.0 under 2 seconds
let tween = Tween::new(1.0, Duration::from_secs(2))
let mut anim = tween.start(val);
// Update tween anim.progress(&mut val, Duration::from_millis(200)) ```
