Change json command format
Created by: dominikwerder
Change the JSON command format for start file writing where the streams are now embedded in the nexus_structure
hierarchy, example shown in README.md
. Closes #17 (closed).
In the new format the responsible file writer module is specified up front in the json command and no longer inferred from the first arriving flatbuffer message. Therefore, also the way interface for the file writer modules has changed, see CHANGELOG.md
.
