A simple module to search parent directories for config file
Problem...
You want to install a project from a repository and use application configuration variables that depend on the file system location the repository is installed in.
Solution ...
configVars = require('parent-config')('myConfig.json')
This will search the parent directories of the project folder for the file myConfig.json and then parse the first file it finds. If the file doesn't exist or there is a json parse error then an empty object is returned.
This allows you to clone a git project into different locations and have the code know it's environment. An example would be to have one myConfig.json file in the same folder as the project for production and another myConfig.json file in a development folder.
