/**
 * @class AliHLTAltroChannelSelectorComponent
 * A selector component for ALTRO Raw data. The component subscribes
 * to the RAW data {***:DDL_RAW } and gets in addition a list of channels
 * to select. The list must be of identical specification as the RAW data
 * and can be of data type:
 * - {***:HWADDR16}: 16 bit hardware addresses
 *
 * In Oct 2008 the component has been extended in order to select channels
 * by calculating average/sigma and applying thresholds.
 *
 * The AliAltroRawStreamV3 is used as input decoder to read and scan the
 * Altro Raw data.
 * 
 * <h2>General properties:</h2>

 * Component ID: \b AltroChannelSelector                                <br>
 * Library: \b libAliHLTRCU                                             <br>
 * Input Data Types: kAliHLTDataTypeDDLRaw, kAliHLTDataTypeHwAddr16	<br>
 * Output Data Types: kAliHLTDataTypeDDLRaw                             <br>

 * Mandatory arguments: <br>
 * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting -->
 *
 * Optional arguments: <br>
 * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting -->
 * \li -keep-corrupted
 *     keep corrupted channels, by default ignored
 * \li -talkative
 *     be a bit more verbose, prints out statistics message and warnings
 * \li -start-timebin <i> bin </i>
 *     all time bins below will be ignored    
 * \li -end-timebin <i> bin </i>
 *     all time bins above will be ignored    
 * \li -signal-threshold <i> adc_counts </i>
 *     the average will be calculated from all bins between start and end,
 *     a channel is considered active if the maximum is bigger than averge
 *     plus threshold
 * \li -rms-threshold <i> sigma </i>
