Move DigitizationPlugin to Fatras
The Digitization
and PlanarCluster
creation is currently in core but belongs clearly into the fast simulation repository.
At this stage, the IdentificationPlugin
mechanism can go, as the identifier definition can move fully to the downstream client.
We will have to understand where to put the SpacePointBuilder
code, but that could probably be simplified and made independent of the PlanarModuleCluster
class.
