Pass in a random value seed to cluster initialization functions #18

I'm using this library in a context where I need the results to be deterministic. Would it be possible to provide the option to pass a seed into the cluster initialization functions?

I was thinking an optional argument could be passed into the skmeans function called seed and that would be passed on to the kmpp and kmrand .

I am able to implement this functionality, I just want to make sure that this is behavior that library owners want.

Thanks!
