Document Vardict Filtering

[buehlere]

Provide documentation for how vcf filtering works in this file on the re-project-layout branch .

I think we need to describe:

• Purpose of filtering
• difference between single and case-control

Here's where the filtering code currently lives: https://github.com/msk-access/postprocessing_variant_calls/blob/re-project-layout/src/vardict/vardict_class.py.

This documentation is linked to our gitbook for the package!
