Normalizer

class Normalizer extends VectorTransformer

:: Experimental :: Normalizes samples individually to unit Lp norm

For any 1 <= p < Double.PositiveInfinity, normalizes samples using sum(abs(vector).p)(1/p) as norm.

For p = Double.PositiveInfinity, max(abs(vector)) will be used as norm for normalization.
