/**
 * Helper macro to format a block of AliHLTComponentStatistics entries.
 * The block is usually created by attaching a file writer to a chain,
 * writing only COMPSTAT:PRIV data blocks.
 *
 * The macro translates the block into HLTruns a stand-alone chain
 * Usage:
 * <pre>
 *   aliroot -b -q format-statistics.C | tee format-statistics.log
 * </pre>
 *
 *
 * @ingroup alihlt_benchmark
