 First the similarities. Bodies, geoms and sites all have spatial frames attached to them (although bodies also have a
 second frame which is centered at the body center of mass and aligned with the principal axes of inertia). The positions
 and orientations of these frames are computed at each time step from ``mjData.qpos`` via forward kinematics. The results

 Now the differences. Bodies are used to construct the kinematic tree and are containers for other elements, including
