Config consolidations
- The
remapping
field in the DL2 block is optional, ticking a box in #51 (closed). The code checks all keys are used to avoid silent misspelling mistakes etc. - Move Dl2 config to nlohmann
- Remove GNN configs in favour of using
EMPFlowAll.json
. Keep thegnn-track-cuts.json
as this is still under study. - Consolidate variables between files where possible.
