license-compatibility-checker

Check npm dependencies' package.json for license compatibility (aka compliance check) with the current project based on spdx notation and naming conventions.

This is WIP and likely to change but already useable.

Does a simple comparison like Public Domain > Permissive > Weakly Protective > Strongly Protective > Network Protective of the primary dependencies in node_modules (no recursive search). Checks for unlicensed or unknown licenses.
