Implementation of Standard scaler ( #143 )
...
* 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`.

Categorizable trait defines logic of turning floats into hashable categorical variables. Since we only support RealNumbers for now, the idea is to treat round numbers as ordinal (or nominal if user chooses to ignore order) categories.
