//
//   This macro shows how to read the Individual Pixel Rates from 
//   a CC report file.
//
//   Input: 
//     - root file obtained merpping a .rep CC file
//       container: MTriggerIPR
//
//   Output:
//     - a camera display showing the IPRs
//     - Some histos for checking purposes
//   
//   Note: 
//     a similar macro can be used to read the following trigger containers:
//     - MTriggerIPR        (Individual Pixel Rates)
//     - MTriggerCell       (Rate of trigger cells)
//     - MTriggerBit        (Output Bits from prescaler (before/after presc.)
//     - MTriggerPrescFact  (Prescaling factors for each bit)
//     - MTriggerLiveTime   (Values of counters for dead/livetime)
