Initial addition

@ewels here it is :+1: 

This is WIP repo, so can be merged without a review (for now) :)
@guillermo-carrasco @mariogiov @Galithil - anyone have any thoughts on this? @senthil10 suggested that we keep the report_templates folder in the config file. I prefer to figure out the directory based on the location of the currently executed file (IMHO the less in the config file, the less there is to go wrong). However, this is a bit messy. Anyone have any favourites?
