Changes the design of the plugin to work with multiple, independent
high-precision hierarchies at the root with the `BigSpace` component at
the root of each of these hierarchies.
Closes#17Closes#19Closes#21
Adds the concept of reference frames, allowing hierarchies of high
precision objects, e.g. objects in the reference frame of a planet,
which is itself rotating, and orbiting about a star.

I ran into an issue when trying to add the transform propagation systems
to a schedule more than once. The app would panic because there was more
than one instance of `propagate_transforms::<P>` and
`recenter_transform_on_grid::<P>` in the system graph, so Bevy didn't
know how to actually resolve the dependencies. By using a `SystemSet`,
we can avoid this issue nicely.
Unfortunately, I couldn't come up with a good name for the set, so I
decided to stick the definition inside the `build()` method itself. That
way at least the poor naming won't be exposed 😛. It still feels a little
icky to me though.
