d864ab5abe Drop second attempt at static matrices 
I couldn't get this one working, and the first attempt seems fine.

fb51e00503 Remove unnecessary type annotations 
These annotations are only needed for statically sized matrices.

144bfb8faf Scala benchmark: use fullLinkJS output 
The JavaScript produced by `fullLinkJS` is about twice as fast as the
code produced by `fastLinkJS`.

42bdfabd91 Rust trial: port interface to Sycamore 
Now we have a reactive web app written entirely in Rust. The Trunk build
tool compiles it to WebAssembly and generates a little JavaScript glue.

12abef4076 Trial a Rust engine powering a Civet interface 
Write a basic web app with a Rust engine, compiled to WebAssembly,
powering a Civet interface. Do linear algebra in the engine using
the `nalgebra` crate.

d7dbee4c05 Stow algebraic engine prototype 
We're using the Gram matrix engine for the next stage of development,
so the algebraic engine shouldn't be at the top level anymore.

9d69a900e2 Irisawa hexlet: use Abe's terminology in comments

spheres.

8a77cd7484 Irisawa hexlet: drop unviable approach 
The approach in the deleted file can't work, because the "sun" and
"moon" spheres can't be placed arbitrarily.

problem.

a7f9545a37 Circles in triangle: correct frozen variables 
Since the self-product of the point at infinity is left unspecified, the
first three components can vary without violating any constraints. To
keep the point at infinity where it's supposed to be, we freeze all of
its components.

d0340c0b65 Correct point utility again 
The balance between the light cone basis vectors was wrong, throwing the
point's coordinates off by a factor of two.

5abd4ca6e1 Revert "Give spheres positive radii in examples" 
This reverts commit 4728959ae0, which
actually gave the spheres negative radii! I got confused by the sign
convention differences between the notes and the engine.

4728959ae0 Give spheres positive radii in examples 
This changes the meaning of `indep_val` in the overlapping pyramids
example, so we adjust `indep_val` to get a nice-looking construction.

b185fd4b83 Switch to backtracking Newton's method in Optim 
This performs much better than the trust region Newton's method for the
actual `circles-in-triangle` problem. (The trust region method performs
better for the simplified problem produced by the conversion bug.)
