 Marshmallow package provides a simple API to perform flexible and
 performant JSON unmarshalling in Go.
 .
 Marshmallow specializes in dealing with **unstructured struct** - when
 some fields are known and some aren't, with zero performance overhead
 nor extra coding needed. While unmarshalling, marshmallow allows fully
 retaining the original data and access it via a typed struct and a
 dynamic map.
