* @class AliHLTMUONHitReconstructorComponent
* @brief A processing component for the dHLT tracker DDL reconstruction.
+ *
+ * This is the hit reconstruction component which forms part of the online dHLT
+ * reconstruction algorithm. It processes the raw DDL data from a dimuon spectrometer
+ * tracker station, applies simple 3 pad cluster finding and then a centre of gravity
+ * calculation to reconstruct the hit coordinate.
+ *
+ * <h2>General properties:</h2>
+ *
+ * Component ID: \b MUONHitReconstructor <br>
+ * Library: \b libAliHLTMUON.so <br>
+ * Input Data Types: ('DDL_RAW ', 'MUON') <br>
+ * Output Data Types: ('RECHITS ', 'MUON') <br>
+ *
+ * <h2>Mandatory arguments:</h2>
+ * \li -ddl <i>number</i> <br>
+ * This indicates the DDL from which the component is expect to receive data
+ * and for which it should load the appropriate electronics mapping lookup
+ * table.
+ * The <i>number</i> should be in the range [13..20], following local dimuon
+ * spectrometer DDL numbering. If either the -ddlid, -lut or -delaysetup
+ * arguments are used, then -ddl becomes optional. <br>
+ * \li -ddlid <i>number</i> <br>
+ * This indicates the DDL by equipment ID, from which the component is expect
+ * to receive data and for which it should load the appropriate electronics
+ * mapping lookup table.
+ * The <i>number</i> should be in the range [2572..2579].
+ * If either the -ddl, -lut or -delaysetup arguments are used, then -ddlid
+ * becomes optional. <br>
+ * \li -delaysetup <br>
+ * Specifying this option causes the component to initialise the lookup table
+ * and DC cut parameters from CDB only after receiving the first event to
+ * process in DoEvent.
+ * If -ddl or -ddlid were not used, then the DDL number will be taken from
+ * the first block's specification during runtime from the first
+ * event (Start-of-Run event).
+ * Using the -lut or -dccut arguments will override loading from CDB for a
+ * delayed setup. <br>
+ *
+ * <h2>Optional arguments:</h2>
+ * \li -lut <i>filename</i> <br>
+ * A pree-built lookup table for the electronics mapping and calibration
+ * information can be loaded with this argument. The file should have been
+ * generated with the GenerateLookupTable method. The location of the file
+ * is given by the parameter <i>filename</i> <br>
+ * \li -cdb <br>
+ * Indicates that the component should load from CDB. This option is implicit
+ * if the -cdbpath is given. It will also override the -lut option.<br>
+ * \li -cdbpath <i>path</i> <br>
+ * Specifies the CDB path to use, given by <i>path</i>. This option will override
+ * the CDB path automatically set by the HLT framework. <br>
+ * \li -run <i>number</i> <br>
+ * Specifies the run number to use, given by <i>number</i>. This option will
+ * override the current run number automatically set by the HLT framework. <br>
+ * \li -dccut <i>number</i> <br>
+ * Used to override the DC cut parameter in the CDB with the value given by
+ * <i>number</i>. <br>
+ * \li -warn_on_unexpected_block <br>
+ * This will cause the component to generate warnings when it receives data block
+ * types it does not know how to handle. Without this option the component only
+ * generates debug messages when they are compiled in. <br>
+ * \li -tryrecover <br>
+ * This is a special option to the raw data decoder to turn on logic which will
+ * try and recover from corrupt raw DDL data. This is off by default. <br>
+ *
+ * <h2>Standard configuration:</h2>
+ * This component should normally be configured with either of the two sets of
+ * options in the XML configuration. <br>
+ * \li -delaysetup <br>
+ * \li -ddlid ${DDL_ID} <br>
+ *
+ * <h2>Default CDB entries:</h2>
+ * The component loads electronics mapping and calibration information from the MUON
+ * subdirectory in the CDB, MUON/Calib and MUON/Align.
+ * The DC cut parameter is stored in a TMap under HLT/ConfigMUON/HitReconstructor
+ * with a default value of 50 ADC channels.
+ *
+ * <h2>Performance:</h2>
+ * Can achieve about 2kHz processing rate for nominal event sizes containing
+ * 150 tracks per event.
+ *
+ * <h2>Memory consumption:</h2>
+ * The lookup table requires about 3.5 MBytes of memory.
+ *
+ * <h2>Output size:</h2>
+ * Output size is about 10% of incoming raw input data for nominal p+p events.
