Namespaces
namespace	o2
	a couple of static helper functions to create timestamp values for CCDB queries or override obsolete objects

namespace	o2::framework
	Defining PrimaryVertex explicitly as messageable.

namespace	o2::mergers

namespace	o2::mergers::object_store_helpers

Typedefs
using	o2::mergers::TObjectPtr = std::shared_ptr< TObject >

using	o2::mergers::VectorOfRawTObjects = std::vector< TObject * >

using	o2::mergers::VectorOfTObjectPtrs = std::vector< TObjectPtr >

using	o2::mergers::MergeInterfacePtr = std::shared_ptr< MergeInterface >

using	o2::mergers::ObjectStore = std::variant< std::monostate, TObjectPtr, VectorOfTObjectPtrs, MergeInterfacePtr >

Functions
ObjectStore	o2::mergers::object_store_helpers::extractObjectFrom (const framework::DataRef &ref)
	Takes a DataRef, deserializes it (if type is supported) and puts into an ObjectStore.

VectorOfRawTObjects	o2::mergers::object_store_helpers::toRawObserverPointers (const VectorOfTObjectPtrs &)
	Helper function that converts vector of smart pointers to the vector of raw pointers that is serializable. Make sure that original vector lives longer than the observer vector to avoid undefined behavior.

bool	o2::mergers::object_store_helpers::snapshot (framework::DataAllocator &allocator, const header::DataHeader::SubSpecificationType subSpec, const ObjectStore &mergedObject)
	Used in FullHistorMerger's and IntegratingMerger's publish function. Checks mergedObject for every state that is NOT monostate and creates snapshot of underlying object to the framework.
