4.4 beta 1 new Humanoid Animation features

We need to start thinking what demos to add to this repository to add to this project that reflects the latest changes in 4.4 beta 1 for humanoid animation

Many of these new features come with toy demo projects, we need to figure out how to organize these demos in this repository to accommodate the latest updates in humanoid animation.
