### TODO
- pin feets:
- iterate in reverse in keys when pinning so last foot position is correct
- create intermediate keys (at each frame when necessary) to prevent lateral sliding on curved path
(maybe expose as an option... not needed if path is straight for example... or auto detect if path is full straight at the moment of pin ops)
- Expose methods to go back in action history
*things to consider*:
- Expose foot ?
- Store path animation on a separate action (but that mean NLA hadto be used every time)
Bonus:
- Use position A-B method to generate curve (with retimed animation to prioritize speed over fidelity)
- auto-determine foot bone to use for distance reference
- Better A-B position setup:
- auto-retime animation to prioritize speed over base cycle velocity
- create nurb path instead of curve
- Smoothing keys after last freezed to avoid too much gap "pose click".
<!--
### DONE
- auto-determine foot bone to use for distance reference
- Expose methods to go back in action history
- pin feets:

- create intermediate keys (at each frame when necessary) to prevent lateral sliding on curved path
(maybe expose as an option... not needed if path is straight for example... or auto detect if path is full straight at the moment of pin ops)
- align curve to root
- Put curve forward motion on bones modifier's offset value as negative time offset (instead of using curve )
