@bdice since we're thinking about making 3.0 due to #738, this should also be done for that (at least renaming the existing options, whether or not the new normalization features...

@tommy-waltmann to speed up 3.0 I would recommend just doing the renaming of existing normalizations without implementing new normalization solutions.

@klywang any updates on this?

Just to clarify for whoever chooses to write this up in the future: the `random_quaternions` above are just for demonstration. The usage example should just start on the line `orientations...

Yeah I think the only places that I recall finding satisfactory explanations for the nematic tensor, the director, and the order parameter were published papers. All other sources were definitely...

I believe that #1292 fixes #1282. This issue was opened by @tommy-waltmann to track future work.

Prior to the voro++ switch the voronoi module was using double precision (unlike everything else in freud that uses single precision), but since we switched to voro++ I don't know...

Yeah I'm fine relaxing the tolerances in the test. Voronoi is a tricky case because despite the calculations being in double precision we still run into these problems, which make...

I would suggest being more explicit with the naming. Rather than `PotentialPairBase`, leave `PotentialPair` as the base class and create `PotentialPairIso`.

The [msd module](https://github.com/glotzerlab/freud/blob/master/freud/msd.pyx#L54) includes the core implementation of an autocorrelation function. I think I just left it internal because it was relatively simple and doesn't need the usual freud machinery....
