What is this good for?

And why is East Frisia a country?

> const int EAST_FRISIA = 13;

> Gender\Gender::EAST_FRISIA

I think the "Introduction" and "Examples" links on the page make it clear. "The main purpose is to find out the gender of firstnames"

Thanks. Totally missed them because on my phone they show up empty unless you choose the navigation at the bottom of the page.
