> `Bucketizer` maps a column of continuous features to a column of feature
> buckets, where the buckets are specified by users.
> {code}
> val bucketizer = new Bucketizer()
> .setInputCol("age")
> .setBuckets(Array(10, 20, 30, 40, 50))
> .setOutputCol("ageBuckets")

> discuss the behavior if a value falls out the specified bucket range.
