Feature vcf with vcf peter

Needed this tool for data that must be ready this Monday. While running this I found some issues that i fixed in this branch:
- Type is kept from secondary vcf file, this makes filtering later much easier.
- Field in secondary vcf can be different as in output vcf, otherwise records can overritten
- raise errors when field already exist in input vcf or field are missing in secondary vcf
- Style changes, lot of var names with '_', converted to camelCaps

Feature auto memory

Implementation for #136, not yet tested but this should work I think.

See merge request !139

Feature gentrap docs

As we discussed earlier, this is the docs addition to Gentrap and other tools that it uses. I think this should make all the docs for ScalaDoc complete (for the tools I've written).

Please let me know if that is not the case :) ~ so I can add them.
