* AliFMDBaseDA::Rotate(const char* file, int max)
'log-rotates' files that start with 'file' up to a maximum of 'max'.
This is applied to all FXS files (peds.csv, gains.csv, conditions.csv)
as well as zero-suppression files.
* Added comment line in each output file, that tells us from which run
the file was created, and when.
* Fixed some coding violations.
