Initial addition

@ewels here it is :+1: 

This is WIP repo, so can be merged without a review (for now) :)
the templates dir is part of the package, it is not something optional and will always be at the same place (or should...). I would vote for your suggestion in this case @ewels . But yeas looks a bit messy, can't you specify the templates dir on a nicer way with the framework you're using?
