It's also (as it happens) a special case of `Diffraction2D.apply_affine_transformation()`. Shall we use this thread as a place to keep track of such duplications?

I've been thinking about what we're likely to want in 0.14 recently, and I think this high (near top) on that agenda. Can I get back to you on specifics?

`CrystalMap.is_in_data` is pleasing unambiguous... I checked LIBERTEM, they use `1` to mean "included in data" too.

I think we should copy+paste the 0.18 implementation into pyxem as a short term solution. @CSSFrancis do you think that makes sense?

I think some generators (generally those that take two complicated pyxem classes) are an asset to the code. That said I think we've been a bit generous with what we...

You're doing a good portion of the development at the moment, so I'm not at all worried about timings.
