Plugin is for editing walk-cycle animations with the unique ability to correct animations so that they result in a physically plausible motion.

Features:

* Walk-cycle extraction. If you have a non-cycling animation the plugin will find a fragment that can be converted into a walk-cycle in the best possible fashion
* Smooth motion and remove the non-smooth start-end transition
* Fix foot slippage
* Change limb lengths, motion magnitude and mass balance
* Change walk-cycle style such as crouch more/less or walk faster/slower
* Enforce physical correctness
