Switch to Euclidean-invariant projection onto tangent space of solution variety

Reproduction

I've reproduced most of what you describe using the following steps:

  1. Set the Lorentz product between Deimos and Pollux to 1
  2. Select Deimos and then focus the…

Find the tangent space of the solution variety

This issue has been addressed by #29, and the questions it raised now have their own issues: #31 and #35. Is there anything else we need to do before closing it?

Switch to Euclidean-invariant projection onto tangent space of solution variety

I've added tests for #32 and #33, as described in the updated PR description, so the PR is ready for review again!

Switch to Euclidean-invariant projection onto tangent space of solution variety

I realize we don't really have a comprehensive in-source doc system set up yet. I know we discussed it but I forget what we concluded.

I think we decided it would be fine for now to document…

Switch to Euclidean-invariant projection onto tangent space of solution variety

Yes, since the claim is to resolve #32 and #33 when this is merged, it would be good for it to have these two explicit tests connected to those two issues included in this PR.

I'll switch the…

Switch to Euclidean-invariant projection onto tangent space of solution variety

I just checked by hand that the twisting motion printed by the kaleidocycle example is an actual first-order motion of the kaleidocycle. That means we could reasonably turn the kaleidocycle…

I see there were two batches of commits. Is this PR ready for review?

Yes, it's ready for review—I just forgot to push the second batch of commits before posting the pull request. There are…
