Step 1: install AdePT and run the examples
Step 2: understand how Example17 works (integration with native Geant4 application).
Step 3: start playing with Example17 settings in the provided macros, change geometry to some LHCb setup, gun parameters
Note: These examples are not yet efficient in MT mode, we are working on a better interplay scenario with Geant4 at this point
Step4: adapt the scoring (which is done in Example17 via the BasicScoring struct) to your needs
Note: Scoring may require navigation history to identify sensitive volumes and their parents, this can be done via the NavStateIndex interface. We will work on a utility to unify the access to this information depending if the scoring code has to act in the Geant4 or GPU environments. For the moment we have to have different codes for identifying the sensitive volumes on CPU/GPU
Step5: Start integrating with Gaussino ...
