v2.2
Added new functionality:
- added option --filter_readorientation that uses gatk's LearnReadOrientationModel in filtering step (for gatk4)
Minor changes:
- corrected source for docker container (previously on nalcala instead of IARCbioinfo)
- debug multi-sample
- ensures that symlinks to split beds are created (helps running with singularity)
- correctly set up deploy of dags produced during circleci tests to github
- change tempdir for sort for smoother use of singularity
- improved readme with schematic workflow
