The documentation would be vastly more useful with some example code snippets. @klarh I'd appreciate your thoughts on this:

• Do you want to include examples as a git submodule, as we've done for freud and fresnel (to keep the repo size reasonable)?
• Should examples be based on https://github.com/glotzerlab/plato-gallery (should that repo be expanded to include more simple figures)?
• What backends should we showcase for examples? Interactive vs. ray-traced?
• Should the notebooks be pre-rendered (requires a dev machine or Docker image that works with all/most backends) or rendered on ReadTheDocs (potentially time-intensive, hard to configure dependencies)?
