def self.binary(binary, definition_filename, table_name)
  config = TableConfig.process_file(definition_filename)
  load_binary(config, binary)
  return config.table(table_name).buffer
end

.build_json_hash(binary, definition_filename) ⇒ Object

We build the json hash without converting to a json string to allow modifying the hash app/models/table.rb uses this ability to add the real definition filename
