          # This methods accepts input data and type and creates corresponding

          # entity. If necessary, type's factory may be called to instantiate

          # entity.

          #

          # Method is provided with context and fallback block (with same

          # signature) that allows to use default denormalization process. This

          # allows denormalizer to use context to populate entity or use

          # fallback block before or after processing:

          #

          # ```ruby

          # data = { id: data } if data.is_a?(String) || data.is_a?(Symbol)

          # yield(data, type, context)

          # entity.id = entity.id || context.path.current.name

          # entity

          # ```

          #

          # This method should not attempt to denormalize attributes, since that

          # would be taken care of by mapper itself.
