Clustering doesn't work. about igel

[nidhaloff]

@iwantofun thanks for noticing this. Indeed numpy arrays are not JSON compatible that's what the error is saying. This is a bug that I will fix now and draft a new release.

It is also interesting that the data are read and no error was thrown since your data is a .txt and igel supports only csv (at least for now) and make use of the column names to determine which target you want to predict (since you are providing this in the target field in the yaml file). In your case you are providing x and y as a target, but where does these come from? As I can see your txt file is not labeled with an x and y column names

I just added an example for using clustering now. You can check it out and give me a feedback.
