/**
 * @class  AliHLTTriggerPhosClusterEnergy
 * HLT trigger component for high energy clusters in PHOS
 * 
 * Triggers on PHOS clusters containing energy > threshold value. 
 * Configurable through database entry or from command line using "-energy" option
 *
 * <h2>General properties:</h2>
 *
 * Component ID: \b PhosClusterEnergyTrigger                             <br>
 * Library: \b libAliHLTTrigger.so                                        <br>
 * Input Data Types:  kAliHLTDataTypeESDObject, kAliHLTDataTypeESDTree    <br>
 * Output Data Types: ::kAliHLTAnyDataType                                <br>
 *
 * <h2>Mandatory arguments:</h2>
 * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting -->
