class AliDCSSensor: public TNamed

  Standard constructor

  Copy constructor

 assignment operator

 print function

 draw function - to viusalize sensor
 Unfortuantelly - it  make a memory leak as function Draw does not return the object pointer

 Get DCS value for actual sensor
  timeSec given as offset from start-of-map measured in seconds
  *NOTE* In the current TPC setup, start-of-map is defined as the
         first measured point for each sensor. This will be different
         for each sensor in the array. If you want to get a value at the
         same absolute time, use AliDCSSensor::GetValue(TTimeStamp time)
         or AliDCSSensorArray::GetValue (UInt_t timeSec, Int_t sensor)
         which measure offsets with respect to the (global) start-of-run

 Get DCS value for actual sensor
  time given as absolute TTimeStamp

 Return DCS value at given time
  The value is calculated from the AliSplineFit, if a fit is not available
    the most recent reading from the Graph of DCS points is returned (if
    the graph is present)
  If time < start of map  return value at start of map, inside = false
  If time > end of map    return value at end of map, inside = false

 Return DCS value from graph of DCS points (i.e return last reading before
  the time specified by TTimeStamp
  If time < start of map  return value at start of map, inside = false
  If time > end of map    return value at end of map, inside = false

 Extract last value in graph observed before time given by timeHour

 Make graph from start time to end time of DCS values
