/**
* @file
* Helper templates definitions for serializing/deserializing common objects.
*
* Usage:
* You need to (partially) specialize SerializeHelper for your type.
* The optional SFINAE argument can be used to provide generic specializations
* via std::enable_if_t<T>.
* If both paths are common, you can templatize operator()'s first argument,
* but you will need to templatize the passed value to account for different value categories.
*
* See SerializedTypes.h for some examples.
