Read environment variables as settings to build 12-factor apps.

Please see the README at https://github.com/NoRedInk/haskell-libraries/tree/trunk/nri-env-parser#readme.

nri-env-parser

The 12-factor app uses environment variables for configuration. A Haskell app will need to parse environmental values into types. This library provides functionality to do so for commonly used types.

It also provides a way to generate an overview of all environment variables an app consumes.
