Expose a function to register new names

[flesler]

So I found other lists of names, would be cool to merge the list but still use this library for its initial list and all the normalization.

Could add a gender.add(name, gender, lang='en') function and/or gender.setMale(name, lang='en')/gender.setFemale(name, lang='en')

If you can do the normalization to the incoming names, it would be less performance but great because other lists are not normalized (lower case, no weird characters, etc)

We can update the list with other lists if you want, merging them.

Yes I can add a method that add/overwrite a name/gender, but it will remain only in memory. Is this what you ask?
