* Benchmark all files provided through array @fileNamesTable.
30
* All files must be valid, otherwise benchmark fails.
31
* Roundtrip measurements are done for each file individually, but
32
* unless BMK_setBenchSeparately() is set, all results are agglomerated.
33
* The method benchmarks all compression levels from @cLevelStart to @cLevelLast,
34
* both inclusive, providing one result per compression level.
35
* If @cLevelLast <= @cLevelStart, BMK_benchFiles() benchmarks @cLevelStart only.
36
* @dictFileName is optional, it's possible to provide NULL.
37
* When provided, compression and decompression use the specified file as dictionary.
38
* Only one dictionary can be provided, in which case it's applied to all benchmarked files.
