* Provide SupervisedEstimator with a constructor to avoid explicit dynamical box allocation in 'cross_validate' and 'cross_validate_predict' as required by the use of 'dyn' as per Rust 2021
* Implement getters to use as_ref() in src/neighbors
* Implement getters to use as_ref() in src/naive_bayes
* Implement getters to use as_ref() in src/linear
* Add Clone to src/naive_bayes
* Change signature for cross_validate and other model_selection functions to abide to use of dyn in Rust 2021
* Implement ndarray-bindings. Remove FloatNumber from implementations
* Drop nalgebra-bindings support (as decided in conf-call to go for ndarray)
* Remove benches. Benches will have their own repo at smartcore-benches
* Implement SVC
* Implement SVC serialization. Move search parameters in dedicated module
* Implement SVR. Definitely too slow
* Fix compilation issues for wasm (#202)

* grid search draft
* hyperparam search for linear estimators
* grid search for ensembles
* support grid search for more algos
* grid search for unsupervised algos
* minor cleanup
* feat: Add interface to build `Matrix` from rows.
* feat: Add option to derive `RealNumber` from string.
To construct a `Matrix` from csv, and therefore from string, I need to be able to deserialize a generic `RealNumber` from string.
* feat: Implement `Matrix::read_csv`.
* docs: Fix typo in doc for categorical transformer.
* feat: Add option to take a column from Matrix.
I created the method `Matrix::take_column` that uses the `Matrix::take`-interface to extract a single column from a matrix. I need that feature in the implementation of `StandardScaler`.
* feat: Add `StandardScaler`.

Prior to this change, the find function implementation for the
CoverTree class could have potentially returned the wrong result
in cases where there were multiple points in the dataset
equidistant from p. For example, the current test passed for k=3
but failed to produce the correct result for k=4 (it claimed that
3, 4, 5, and 7 were the 4 closest points to 5 in the dataset
rather than 3, 4, 5, and 6). Sorting the neighbors vector before
collecting the first k values from it resolved this issue.
