Install NPM

[RyanSquared]

NPM seems to have split off from Node, and is in a separate package. It should be installed, but is not.

NPM and Node should be installed and managed by users. This will allow them to use the version(s) they need and not force upgrade users that may be running older versions. We could set this up be default for all current users (via nvm and our current node version) and then just have new users install that instead
