TPhTopoData
 
 
- With this “topology” we can create data structures of different “depths”
- 
- “Channel Depth” - one entry for each channel
- “Chip Depth” - one entry for each chip (e.g. for CMN studies…)
- etc.
 
- The contents of this structure can in principle be any object (       working w/ templates in CINT)
- 
- Integer, Float, etc.
- Any TObject - TPhHistogram, TPhCalibration, TPhFrog, etc.
