Overview

A class to dynamically build paths based on parameters Constructed with a pattern like: /test_data/:product/:state/:env Each string beginning with a colon will be replaced from either the params hash passed to the initializer, the “extra_params” hash passed to resolve or environment variables (via Nenv). extra_params is merged into the instance level params hash before resolution
