def initialize(&block)
  hash = DeepHash.new                                # Here's a hook that changes variables storage class.
  block.call(hash)                                   # We're passing this hash to initialize block (see metadata.rb example)
  json = hash.to_json                                # Then we changes the type of it to json, then to OpenStruct.
  @data = JSON.parse(json, object_class: OpenStruct) # Now we can use any variable as @var.l1.l2.l3.l4.l5 and so on
end
