/**
 * @class  AliHLTRunStatistics
 * @brief  Base class for run statistics, for all detectors
 *
 * The run statistic classes hold information / histograms about certain 
 * characteristica of the processed events. They are devided into 3 parts. 
 * A base class  @see AliHLTRunStatistics for general Information, detector 
 * specific classes like @see AliHLTTPCRunStatistics for the TPC and a summary 
 * class @see AliHLTRunStatisticsSummary which can hold several detector classes.
 *
 * This is the base class.
 *
 * Currently implemented detecor classes <br>
