* 2 introduced June 07, enhanced/cleaned/arranged structure
* 3 2007-11-15 RAW DDL data type added; some inconsistencies fixed
* ('void' and 'any' origins); added signed HLT basic data types
+ * 2007-11-23 origin defines have become variables in conjunction
+ * to be used with the operator| (AliHLTComponentDataType)
+ * 2007-11-24 added trigger structs and ESD tree data type
+ * 4 Component configuration and DCS update events added
+ * gkAliHLTDDLListSize set from 29 to 30 according to new PubSub
+ * specs
+ * 5 Data types for Run and Event summary, and for monitoring added
+ * 6 Common data types for TreeD and TreeR defined
+ * kAliHLTAllDataTypes and kAliHLTDataOriginSample added
+ * kAliHLTDataOriginEMCAL added
+ * kAliHLTDataTypeRunType added
+ * 7 kAliHLTDataTypeComponentStatistics, kAliHLTDataTypeComponentTable,
+ * and AliHLTComponentStatistics have been added for optional
+ * component block statistics
+ * 8 new wrapper interface has been introduced, old wrapper interface
+ * deprecated but kept for backward compatibility, the PubSub
+ * interface is going to be compiled independently of AliHLT, new
+ * interface provided by the libHLTinterface.so
+ * AliHLTComponentEnvironment -> AliHLTAnalysisEnvironment
+ * 9 added data types for arrays of AliHLTExternalTrackParam sets and
+ * TClonesArrays of AliExternalTrackParam objects.
+ * 10 Changes for information objects neededfor running with offline
+ * chains and analysis tasks.
+ * kAliHLTMCObjectDataType added
+ * kAliHLTDataOriginOffline added
+ * kAliHLTDataOriginHLT added
+ * 11 extended AliHLTComponentStatistics: one more member to store the
+ * cycle time between events per component.
+ * 12 added common data type id 'CLUSTERS'
+ * added data type 'ECSPARAM' for the full ECS parameter string to
+ * be sebt during SOR
+ * added kAliHLTDataTypeTrackMC (TRACK_MC) data type
