Imputer
Provides an imputer method which adds missing values to a sparse DataSet of
vectors. Those can be filled with the mean, the median or the most frequent
value of each row or optionally column. Like that incomplete data don't have to
be thrown away, but rather can be used to train a machine learning algorithm

class. One for the rowwise imputing over all vectors and one for the vectorwise
imputing
