Together with @berak I have successfully added patch #559 which contained code for the NeuralGas clustering algorithm. It is completely tranfered towards C++ interfacing.
I am looking for people who have used this kind of algorithm before to test the code and who might succeed in creating some sample. Also people who can create regression tests, feel free to help out. Same goes for documentation, altough I can do this myself.
Easiest way to help out is to fork my repository! If anyone has any recommendations, feel free to add them!
