CsvRowCreator

A transformer that takes a value of a specified input type that produces string-based CSV data.

A: the input type that is transformed into CSV output.
features: a representation of the features used to generate the row ouput.
headers: note that the dimensionality of this vector is equal to the dimensionality of the output vector produced by features rather than the number of features used to produce the vector. This is because categorical variables can be expanded in different ways based on the com.eharmony.aloha.dataset.csv.encoding.Encoding used.
separator: the field separator
