func New 

func New(files ...string) *CSVFiles

New - Returns a `*csvutil.CSVFiles` with the files given.

func (*CSVFiles) GetCSVColumns 

func (cf *CSVFiles) GetCSVColumns(columns ...int) ([][]string, error)

GetCSVColumns - Reads csv lines from *csvutil.CSVFiles and returns the requested columns. If the column lenghts are different, it will error out (necessary here? maybe the caller should check for that.)

func (*CSVFiles) GetFloat64Columns 

func (cf *CSVFiles) GetFloat64Columns(columns ...int) ([][]float64, error)

GetFloat64Columns - given a set of CSV files and a list of columns, it will return those columns as a slice of floats. If filterZero is set, it will ignore Zero values. If the column lenghts are different, it will error out (necessary here? maybe the caller should check for that.)

func (*CSVFiles) PrintCSVRows 

func (cf *CSVFiles) PrintCSVRows(rows ...int) error
