Install a shrinkwrap or package-lock file directly. just pulls down packages and unpacks in the right place. does not mess with package-json or check the shrinkwrap makes sense. Just does what it says on the tin and nothing else.
you may need to run npm rebuild after this script,
if compiling any modules are needed.
- pulls down modules from resolved url (surprisingly, npm doesn't seem to use this!)
- doesn't actually check integrity code
- could check npm's cache for integrity code first.
PRs welcome.
