Apparently the "engines" files of package.json is no longer checked regularly when performing installs. With the changes and different behaviors across different version of Node & NPM, and having no other way to ensure everybody contributing is on the same page, this preinstall check is necessary. This heavily relies on "SemVer" NPM package, but in order to actually check this prior to the first set of packages installed the code needs to be there. So this is a slimmed down version of SemVer and syntax has been updated.
