Publish module js-common to NPM, and then use module.

------

Open GitHub
Add project js-common

go to js-common project dir
add ".gitignore" containing "node_modules"
Add package.json (module entry is "index.js")
push changes using git to remote repo (steps below)

Push changes using git to remote repo:

Open Console
Go to js-common project root dir

# Add new Github repository named 'js-common'
Accept all defaults except select "Add a README file"

# Open bash or desired cli
# Navigate to root of project dir
> git init
> git status
> git add *
> git status
> git commit -m "init"
# Go to Github and copy repository directory path (via "Code" button)
# git remote add origin <repos path>
> git remote add origin https://github.com/gary-peterson/js-common.git
> git push -u -f origin master
# Go to Github
# The default selected branch will likely be 'main'
# Select the desired branch (e.g. 'master')
# Test that the code is present via Code - Download ZIP


Made change to code (modified index.js and package.json)
> git status
> git add *
> git status
> git commit -m "Added export for MatrixTool"
# push
> git push -u -f origin master

Repblish in NPM
> npm publish --access public

Using new library
Add new node.js project "js-common-remote-client"
Add this to package.json:
	"dependencies": {
	    "@garypeterson/js-common": "^1.0.0"
	  },
> npm install

Code
No changes needed, the "local client" code works:
	const
		{MinimalMatrix} = require('@garypeterson/js-common'),
		{Lab} = require('@garypeterson/js-common'),
		etc
