Are all of the entries for a JSON object required? If I'm only interested in spacial tracking (not lineages, or other states), do I need to indicate "label", "states", "probability", or "time"?

Following the Fortran Modernisation workshop...

• Use more modern fortran features
• Use cmake instead of make
• Optimise build interface
• Error handling and exceptions
• Self-documenting code
• Reorganise the repository
• Tests
