Test a scale constraint
...
In all but a few cases (for example, a single point on a plane), we
should be able to us the radius-coradius boost symmetry to make the
average co-radius—representing the "overall scale"—roughly one.

The previous cut was supposed to do this, but I was missing some parentheses.

Seek sample solutions by cutting with a hyperplane
...
The example hyperplane yields a single solution, with multiplicity six. You can
find it analytically by hand, and homotopy continuation finds it numerically.

In the cases I've tried so far, this leads to substantially smaller
Gröbner bases.

You're right: this naming convention seems to be standard for Julia
modules now.

The extension should also let us work over finite fields of prime order,

Order variables by coordinate and then element
...
In other words, order coordinates like
(rₛ₁, rₛ₂, sₛ₁, sₛ₂, xₛ₁, xₛ₂, xₚ₃, yₛ₁, yₛ₂, yₚ₃, zₛ₁, zₛ₂, zₚ₃)
instead of like
(rₛ₁, sₛ₁, xₛ₁, yₛ₁, zₛ₁, rₛ₂, sₛ₂, xₛ₂, yₛ₂, zₛ₂, xₚ₃, yₚ₃, zₚ₃).
In the test cases, this really cuts down the size of the Gröbner basis.

Automatically generate externals.js from package-lock.json
...
This commit adds a utility to parse package-lock.json and write the proper
contents of externals.js to standard output. In addition, if the utility
(src/helpers/pkglock_to_externals.litcoffee) is invoked with a --doc option,
it instead emits a Markdown bulleted list of all of the external dependencies.
