Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(symbol, *_args) ⇒ Object

Fetch the attribute from the underlying merged_fragment or only fragment. Means that record.attribute (ie. record.name) works for convenience and abstracts away the fact that fragments exist rubocop:disable Style/MethodMissing
