entire modules needs documentation, in particular `smartcore::numbers`. Some content is being developed in [smartcore-jupyter](https://github.com/smartcorelib/smartcore-jupyter/tree/main/notebooks) and should be ported to Rust docstrings.

### I'm submitting a - [x] feature request. ### Current Behaviour: Currently `println!("{}", &gnb)` prints: ``` GaussianNB: inner: BaseNaiveBayes { distribution: GaussianNBDistribution { class_labels: [0, 1, 2], class_count: [50, 50,...

`FloatNumber` and `RealNumber` are used inconsistently as the latter is a compound of the former. Some methods accept one or the other, some both. They both works with `PartialOrd`. Need...

Currently `svm/search` is disabled because of lack of deserialization for `Kernel` (see #221). The current implementation requires cloning of the `Kernel` object, but as it is an object-safe trait cloning...

SVR is very slow (try convex optimization)
