/**
* @class AliHLTSampleESDAnalysisComponent
* An example how to implement an HLT ESD analysis component.
* The class features the AliHLTComponent interface for HLT processing
* components. The interface allows to run such components in either
* the (sequential) AliSimulation/AliReconstruction framework or the
* parallel HLT online processing framework.
*
* An example to run the component can be found in macro sampleEsdAnalysis.C
* in the folder HLT/exa.
*
* Component fetches the ESD from the input objects, loops over tracks and
* publishes the tracks in a TObjArray of AliESDtrack.
*
*
General properties:
*
* Component ID: \b SampleESDAnalysis
* Library: \b libAliHLTSample.so
* Input Data Types: @ref kAliHLTDataTypeESDObject
* Output Data Types: @ref kAliHLTDataTypeTObjArray|kAliHLTDataOriginSample
* {ROOTOBAR:SMPL}
*
* Mandatory arguments:
*
* Argument scan is implemented in the function ScanConfigurationArgument().
* see @ref alihltcomponent-initialization-ocdb.
* Please provide specific descriptions and implementations.
* \li -mandatory1 teststring
* an argument with one parameter
*
* Optional arguments:
*
* \li -optional1 teststring
* an argument with one parameter
* \li -optional2
* an argument without parameters
*
* Configuration:
*
*
* Default CDB entries:
* The component has just one default CDB entry in
* HLT/ConfigSample/SampleESDAnalysis.
* It does not load any configuration from the global ConfigHLT
* folder.
* \li -TObjString object holding a string with the configuration parameters
* explained above
*
* Performance:
* The component does not any event data processing.
*
* Memory consumption:
* The component does not any event data processing.
*
* Output size:
* The component has no output data.
