/**
 * @class AliHLTEMCALDigitMakerComponent
 * 
 * Creates the digit used for the clusterizer. Digits are equivalent to the ones in 
 * offline reconstruction
 *
 * <h2>General properties:</h2>
 *
 * Component ID: \b PhosDigitMaker <br>
 * Library: \b libAliHLTEMCAL.so     <br>
 * Input Data Types: @ref AliHLTEMCALDefinitions::fkgChannelDataType<br>
 * Output Data Types: @ref AliHLTEMCALDefinitions::fgkDigitDataType<br>
 *
 * <h2>Mandatory arguments:</h2>
 * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting -->
 * \li No mandatory arguments for component                           <br>
 *
 * <h2>Optional arguments:</h2>
 * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting -->
 * \li -lowgainfactor      <i> value </i> <br>
 *      sets a global low gain factor 
 * \li -highgainfactor <i> value </i> <br>
 *      sets a global high gain factor
 * \li -reverseorder <br>
 *      set if one expects the low gain channels to come before the high gain ones
 *
 * <h2>Configuration:</h2>
 * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting -->
 * \li No configuration arguments 
 *
 * <h2>Default CDB entries:</h2>
 * \li No CDB entry yet, will come.
 *
 * <h2>Performance:</h2>
 * Pretty good
 *
 * <h2>Memory consumption:</h2>
 * Pretty low
 *
 * <h2>Output size:</h2>
 * Depends on the event...
 *
 * More detailed description. (Soon)
