Unfold static Walk/run cycle along defined path.

## Description

sequencial set of tools:

- Fix character on curve
- Fit the curve on a ground object
- Animate the path (use key marked as 'EXTREME' type on selected foot pose bone)
- Define speed and adjust
- Expand anim cycle and step curve animation
- Pin feet on ground (use contact keys marked as 'EXTREME' for each feets)

### Where ?

Sidebar > Anim > unfold anim cycle

### 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
  - create nurb path instead of curve
  - Smoothing keys after last freezed to avoid too much gap "pose click".

<!--
### DONE
- align curve to root
- Put curve forward motion on bones modifier's offset value as negative time offset (instead of using curve )
