Distribution comparison

[Kucharssim]

This adds a tool for comparing various distributions and assessing their fit to data.

@Kucharssim I’ve tested it, and everything works very well. I also don’t have any comments on the code itself.

My only suggestion concerns the GUI. It might be more intuitive to allow users to add distributions through a dropdown menu, checkboxes, or a similar selection mechanism rather than via “code.”

At the moment, I find it somewhat confusing that I have to enter parameter values even when they are estimated freely. For some distributions, I’m not even sure how they are parameterized, so I would essentially be entering arbitrary numbers. Being able to simply select distributions from a list would make the process clearer and avoid that.

Thanks for the review!

Yes, I initially intended to implement the distribution specification using something like TabView with DropDown etc, but this made the GUI (and the QML code behind it) really bloated. I hoped that adding the "preset" buttons and the additional helpfile for the syntax would make this approach more user friendly, but I do agree that it's not ergonomic to be looking at the help file all the time.

I will look into it again if I can find some alternative/compromise solution (or just implement the TabView and will have to live with it :D).
