Overview

Class to handle recursive merging of configuration between platforms, suites, and common data.

This object will mutate the data Hash passed into its constructor and so should not be reused or shared across threads.

If you are squeamish or faint of heart, then you might want to skip this class. Just remember, you were warned. And if you made it this far, be sure to tweet at @fnichol and let him know your fear factor level.
