timeSum, tiny addition to console to measure aggregated time used between two calls and print them and some maintenance around it. ymmv. assumes `console` is global across modules, like it is in nodejs. require once use anywhere

	const { performance } = require("perf_hooks")

	let running = new Map()
	let data = new Map()
	let timeNames = new Set()

	console.timeSum = function _timeSum(name, callback) {
	if (running.has(name)) {
	return console.warn("console.timeSum: name already being recorded:", name)
	}

Silly mocha+babel problem with relative imports outside project root

	How do you mocha+babel test projectA as is?
	Note that projectB also its own mocha+babel tests which run fine (but they do not need to run here).

	// ..../somedir/projectA/src/index.js
	import {x} from '../../projectB/src/index.js';
	...


	// ..../somedir/projectB/src/index.js
	import {x} from './tools.js';

This takes an fdq input problem, solves it, and confirms the result is correct. I use it to test whether transformation tricks are valid, where I don't care about the actual results as long as they are valid. This will automate this process, prevent me from having to write a zillion results by hand, and of course maintain them as they can change…

	import Solver from '../../src/solver';
	import {
	domain__debug,
	domain_arrToSmallest,
	domain_createValue,
	domain_divby,
	domain_intersection,
	domain_mul,
	} from '../../src/domain';
	import domain_plus from '../../src/doms/domain_plus';
