* QuaC is heavily reworked to be a companion pipeline to small variant caller pipeline and will now perform most of the
QC analyses for WGS/WES data. While the small caller pipeline will still run few QC tools (for pragmatic reasons),
QuaC will now take over the heavylifting of QC, including the QC-checkup, which is now called as QuaC-Watch.
* Runs in containerized environment using Singularity.
* QuaC can perform both sample-level and project-level QC. This is the major reason why it was decided to separate QC from small-variant caller pipeline, as it could only perform single-sample QC.
* More QC tools were added
* For QC checkup (ie. QuaC-Watch), QuaC now heavily expands to vcf metrics and adds significant amount of QC thresholds for bam metrics.
