-- Make it easier to change modules from builtin to externally loaded.
-
- have: MODULE_INFO(name, init, destroy, { require} ) in each module.
- Maintain the list of builtin modules and search these first (or
- optionally last). Add the lib prefix if needed to avoid having to
- specify libbatchAnalysis instead of batchAnalysis.
-
- Define formally traceset/trace in the GUI for the user and decide how
trace/traceset sharing goes in the application.
