Detailed Description

Holds the latency and the mode of the run.
The latency is stored per apv and the information is compressed by reducing sequences of apvs with the same latency to a single value plus information on the start and end of the sequence.
The mode is a single value, stored as a char. The actual operation mode bit is bit number 3 starting from 0. The bitmask to retrieve the information in the number 8 (1000).

• (mode & 8) == 0 : deconvolution mode
  
• (mode & 8) == 8 : peak mode
  See here http://cdsweb.cern.ch/record/1069892 page 13 section 5.5 table 7 for the definition of possible modes.
  The put method requires the latency and mode values for a given apv and detId.
  
  The internal Latency object stores the detId and apv value in a compressed (bit shifted) uint32_t holding both the values. It stores the latency value in a uint8_t (unsigned char). The APV user guide reports a maximum value of 191 for the latency, so the uint8_t (0-255) is enough. If the value is not filled or the detId is not found it will return latency = 255.
  The mode value is also stored in an unsigned char (possible values 0-255). The invalid case returns mode = 0 in this case.
  To save space, since typically the latency and mode is the same for all apvs, the ranges of consecutive detIds and apvs are collapsed in the last value, so that the lower_bound binary search will return the correct latency and mode.
  
  Methods are provided to extract latency and mode (separately or together in a pair) for each apv.
  If the value of latency (mode) is the same for the whole Tracker, the singleLatency() (singleMode()) method will return it, otherwise it will return 255 (0).
  
  The method allLatencyAndModes() returns the internal vector<Latency> (by value).
  The method allUniqueLatencyAndModes() returns all the combinations of latency and mode present.
  ATTENTION: This method assumes that latency and mode are stored in a unsinged short.
  The method singleReadOutMode() returns: 1 if all the Tracker is in peak, 0 if it is in deco, -1 if it is in mixed mode
  
  The method allModes (allLatencies) fill the passed vector with all different modes (latencies) in the Tracker.
  ATTENTION: the biggest possible detId value that can be stored is 536870911 because 29 bits out of 32 are reserved for the detId and the remaining 3 for the apv value (1-6).
  The biggest possible Tracker detId at this moment is 470178036 so this is not a problem. In any case the code will throw an "InsertFailure" cms::Exception if trying to insert a detId above the maximum and output a detailed LogError message about the problem.

Saves the detIdAndApv and latency values in the vector of Latency objects. At the end of the filling phase, the compress method should be called to collapse all ranges in single values. Note that everything would work even if the compress method is not called, only the space used would be more than needed.
