.deep_merge_hashes(master_hash, other_hash) ⇒ Object

This code was taken from Jekyll, available under MIT-LICENSE Copyright © 2008-2014 Tom Preston-Werner Merges a master hash with another hash, recursively.

master_hash - the “parent” hash whose values will be overridden other_hash - the other hash whose values will be persisted after the merge

This code was lovingly stolen from some random gem: gemjack.com/gems/tartan-0.1.1/classes/Hash.html
