Hi @yifever - do you need some guidance/help on this to bet it going?

@FabianKlimpel will soon be in the position to merge the #574 in, then we could aim at a Fatras feature release.

[yifever]

Hi @FabianKlimpel and @asalzburger
I took some time to fix all the unit test and formatting. This should be good now

[yifever]

I think I need someone to add a milestone for me. I am not a contributor and I am not sure I have that permission. (I have 0 experience in github and if there is a way for me to do this I apologize in advance for not finding the button.)

[asalzburger]

Ok, set the milestone and triggered merging of master into this, let's see.

[asalzburger]

Naming convention changes & some other small remarks.

[yifever]

Hi @asalzburger Can you look at the new changes?

[paulgessinger]

Let's get this in

I'm overriding the missing coverage results.
