Rename the Element
structure to Sphere
This makes way for an `Element` trait. Some `Sphere` variables, like the arguments of the sphere insertion methods, have been renamed to show that they refer specifically to spheres. Others, like the argument of `ElementOutlineItem`, have kept their general names, because I expect them to become `Element` trait objects.
