// This defines two classes, one that has to be extended to make a new plugin,
// and one that can be used as-is for the Harvesting.
//
// As with the entire SiPixelPhase1Common framework, you do not have to use
// this but can still use the other helpers. However, the HistogramManager
// needs to run in step1 and step2 of the DQM, and need to have exactly the
// same spec to work properly. This has to be guranteed by the configuration.
