language diagram

Very much inspired by all the family diagrams I've stumble on recently (babelkid, multitongue, bilingualism, trilingual+1), here is our language diagram. Still quiet simple. English rules, but who knows what is going to happen in the future... Afrikaans will need to be included soon, once BK is further exposed to environment. And of course, so far there is only one BK around, but hopefully it will change...
