Description

This library analyzes the provided package.json, and returns the packages which version range can be updated to include the latest version only.
Currently, only dependencies and devDependencies are analyzed (feel free to submit a Pull Request if you need more than that).
You can pass a second argument if you don't want to analyze everything. For example, to avoid analyzing dependencies, do:

analyzeDeps(packageJson, { dependencies: false }).then(...)
