Creating Nodes

Notes for improvements

Testing Nodes

Add more information on how to test nodes and provide a test harness. There is a test helper for nodes in the main repo which is reused by node-red-nodes repo that needs documenting and maybe exposing better.

npm link can be a pain on Windows and with npm 5. We should maybe suggest

npm install ../path/to/module

Documentation: https://docs.npmjs.com/cli/install

This creates a direct symlink to the node's npm module code.

For older versions of npm, we can document the direct/manual sym link approach on Windows, and Mac/linux.
