This is a bullet wrapper that allows Godot to use Bullet physics and benefit about all features. Also it support all specific Godot physics functionality like multi shape body, areas, RayShape, etc.. It improve the Joints, Trimesh shape, and add support to soft body even if Godot is not yet ready to it.
