- Use new Gaudi helper class to iterate recursively through all child tools and using the new
  Gaudi visitor which renounces certain inputs from a tool, to renounce the output cluster splitting
  probability map from all child tools. The map is recorded to StoreGate before any of the child tools
  are called. Thus, the map, although not final yet, can already be used through read handles. Without
  renouncing the inputs, Gaudi would issue a circular dependency warning.
- Remove the previously introduced property which allowed to renounce manually the input cluster
  splitting probability map from the PixelClusterOnTrackTool.
