README

This component allows you to merge a number of configuration files together. Typically you may use a .gitignore so that all developers in your team can maintain their own development-environment-specific settings, however this approach allows you to keep a version controlled configuration file which contains the structure and shared contents, and each developer can override their own settings in a seperate file which they control.

The resulting merged configuration will be an array.
