Feature Request: CollisionShape from Vertex list

[arthurfp]

First of all, great job on this project!!! It helped me a lot with my code.

Do you think you can generate a CollisionShape from the google's RendereableDefinition class? Using its vertices?
To every loaded object in Sceneform, Renderable class generates a Box as a CollisionShape, also the HitResult from the Node seems to be the generated Box, which is really bad for 3D objects with other shapes.

I tried to do it, but I couldn't get nowhere. Can you help with that?
