/**
 * @class AliHLTTPCNoiseMapComponent
 * 
 * Implementation of a component to fill histograms with TPC raw output 
 * and read the noise map from HCDB by request.
 * 
 * The component implements the interface methods of the @ref AliHLTProcessor.
 * It reads the raw data pad by pad and fills histograms per partition
 * 
 * The component has the following component arguments:
 * <h2>General properties:</h2>
 *
 * Component ID: \b TPCNoiseMap <br>
 * Library: \b libAliHLTTPC.so     <br>
 * Input Data Types: @ref kAliHLTDataTypeDDLRaw <br>
 * Output Data Types: @ref kAliHLTDataTypeHistogram <br>
 *
 * <h2>Mandatory arguments:</h2>
 *
 * <h2>Optional arguments:</h2>
 * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting -->
 * \li -read-noisemap      <i> teststring   </i> <br>
 *      Reads the noise map from the HCDB (and plots it in a histogram)
 *
 * \li -reset-histograms       <br>
 *      Resets histograms
 *
 * <h2>Configuration:</h2>
 * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting -->
 * \li -config1      <i> teststring   </i> <br>
 *      a configuration argument with one parameter
 * \li -config2                            <br>
 *      a configuration argument without parameters
 *
 * <h2>Default CDB entries:</h2>
 * The component has two CDB entries in
 * <tt>HLT/ConfigTPC/TPCNoiseMapComponent</tt>.
 * It does not load any configuration from the global <tt>ConfigHLT</tt>
 * folder.
 * \li -TObjString object holding a string with the configuration parameters
 *      explained above
 *
 * <h2>Performance:</h2>
 * No clue
 *
 * <h2>Memory consumption:</h2>
 * No clue
 *
 * <h2>Output size:</h2>
 * Much data
 *
 * More detailed description.
