def deep_merge!(target, data)
  merger = proc{|key, v1, v2|
    Hash === v1 && Hash === v2 ? v1.merge(v2, &merger) : v2 }
  target.merge! data, &merger
end

#load!(filename, options = {}) ⇒ Object

This is the main point of entry - we call Settings.load! and provide a name of the file to read as it’s argument. We can also pass in some options, but at the moment it’s being used to allow per-environment overrides in Rails
