Shell Script to Compare Last N Weeks of QA root files

"compare_weekly_test.sh" compares QA ROOT files from the last N weeks located at /lustre/cbm/prod/weekly. It automatically scans the available datasets for different FairSoft versions and across different weeks. For each available dataset, it compares the QA results from the last N weeks and generates output ROOT files.

@s.zharko,I have modified core::qachecker to process histograms using a specific setting config. I’ve attached a sample S100c config file and the corresponding output ROOT file for your review. The modification appears to be working correctly.

However, there is one issue: when I remove the objects node (which is an optional node under the file nodes at the end of the config), the directory for a specific group ends up containing additional histograms that shouldn't be there. I’m currently trying to resolve this issue, but my attempts so far have been unsuccessful. prqa_v18.6.7_apr21p2_weeks_2025_14_15_16_18_19_20_s100c.rootobjects_weekly_s100c.yaml
