npm transitive dependency tree API

Resolve the transitive PRODUCTION dependencies of an npm package@range, with each semver range resolved to a concrete version (depth/size capped). Answers 'full dependency tree of express', 'what does this package pull in transitively', 'how many deps does X have'. The recursive semver resolution is the annoying part.
