Detailed Description

template<is_spawnable T>
struct o2::framework::Spawns< T >

for the automatic table templates

• In a multi-origin case the origin is provided by the type
• In a rewritten origin case the output designation needs to be changed through base class
• The extraction of the elements happens in AnalysisManagers using the origin information from the base class
