Add random forest 2D feature space visualization

I had a commit that had the rename for _normalize ... just pushed that. Also I realize that it's actually Pillow not PIL. in fact the documentation for pillow says...

Add random forest 2D feature space visualization

@tlapusan I think we can close this one right? I think we have the two dimensional future space visualization in.

regression value in dtreeviz doesn't equal to the leaf weight of xgboost dumped model

@tlapusan could this be related to pruning again somehow? in other words, we visualize it correctly but we get the wrong prediction somehow?

hi. yeah, no doubt as they started pruning trees, we might have to look at our shadow model.

ImportError: cannot import name 'Color' from 'colour' (unknown location)

Is there a way for us to simply use an alias or something for the import to avoid a collision?

ImportError: cannot import name 'Color' from 'colour' (unknown location)

Maybe we don't use colour package for very much and can borrow code if under permissive license?

ImportError: cannot import name 'Color' from 'colour' (unknown location)

It looks like the 2-clause BSD license. What is the minimal bit of code we need from them? We could simply pull in the function and then put that license...

labels too close to the axes overlap for classifiers

hahah. yep. that's a good example. thanks!!! Any chance you can send a tiny bit of code we can run as a test for that?

Include more details about tree nodes

Would be good to find a way to provide that in a non-intrusive way.

IndexError: index 22093 is out of bounds for axis 0 with size 22093

Interesting. This is the second report we've seen with XGBoost. @tlapusan maybe this one helps us track it down? We think it could be related to pruning.
