As a developer of Nutrition Information API, I wan't automated dependency management, so I do not have to manually look for new versions of Nutrition Information API's dependencies

Acceptance Criteria

Given a dependency, when it is not the latest version, then automatically create a Pull Request in to master to update it

Test Plan Have an out of date dependency in package.json and see a Pull Request created to update it.

Dev Plan

Update One: -- Originally hoping to use https://greenkeeper.io/ however it does not appear to be working as expected and it is not clear why. When saving the integration, it was expected that out of date dependencies would have Pull Requests opened updating their version. It was also expected that when new versions of dependencies were released on npm, greenkeeper would open a Pull Request with the updated version in package.json. Unfortunately neither of these appeared to happen.
Update Two: -- Then https://www.bithound.io/ was looked at to be used with a different workflow than originally planned. However, bithound requires Full control of private repositories permissions so it will not be used.
Update Three: -- Have tried Greenkeeper again and it worked

Enable GitHub Integration with Greenkeeper for NutritionMate/Nutrition.Information.Api

Documentation Plan Update README.md to include badges for Greenkeeper enabled. This can be done using the following markdown:
