Subject: [PATCH] Configure npm to enforce standard project Node.js version

Various templates use npm package-based tools. The templates are validated for use with a specific major version series
of Node.js. Use of a different major version of Node.js by a contributor may result in spurious problems or unwanted
results.

For this reason, it will be useful to configure npm to produce an error if the contributor uses an unsupported version
of Node.js.
