Before I change status to "QA Ready" on worklist, I have some questions - 

What are these?

- *sittingPoints*
- *script*:  hard to search for this one because “script” appears everywhere
- *mass*: does this come into play into both collisions and gravity?
- *naturalDimentions*: why are they always {x:1, y:1, z:1} ? 

Are these correct?

- *animationFrameIndex* - is the index of the current frame of the animation
- *registrationPoint* - is the default location of an entity from which its co-ordinates are determined. It is used as the point of reference when the entity is moved or rotated.
- *types* - Entities can be one of three types, "Box", "Sphere", and "Model". "Model" types may be animated and take on more complex shapes than Boxes and Spheres.
