names duplicate #7

The error shown when you perform clustering with an array of non unique names is pretty tough to track ...

I suggest to add a check for uniqueness on the arguments here using for instance a new Hashset initialized with the names and compare the size of the hashset with the size of the names array.

Sounds good. Could you send a pull request?

OK, I'll try to have a look at it next week.
