Improving janis-bioinformatics structure

[illusional]

The structure of janis-bioinformatics isn't great, here are some suggestions:

• We grouped tools by their tool provider, but really should've done it by the tool name / base command. Eg:

  • gatk4 tools in a folder called gatk,
  • samtools tools in a folder called samtools,
  • fastqc in a folder called fastqc (not in babrahambioinformatics)

• Reduce the clutter of base.py + versions.py

• Move all the workflows into a folder called workflows

This list is to be updated as new information is discussed
