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.
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.
