Rash is an extension to Hashie

Rash subclasses Hashie::Mash to convert all keys in the hash
to underscore.

The purpose of this is when working w/ Java (or any other apis)
that return hashes (including nested) that have camelCased keys

You will now be able to access those keys through underscored
key names (camelCase still available).
