def mapi[I1 <: Iterable[I2], I2 <: Iterable[S], S, T](data: I1, accum: T)(blockFn: ((Int, T), I2) ⇒ T): (Int, T)

map from the data set to the type T returned by the block function
map from the data set to the type T returned by the block function
blockFn
The blockFn takes the parameters (Int,T), I2 The first paramter is a tuple of (Int, T) which allows the row index to be sent as the first item and the accumulator type of T to be supplied as the second item and returns a type of T which is either the same instance of the accumulator or a new accumulator of same type. The block function allows the CsvReader to transform the data into the accumulator type T.

blockFn
: f(T, mutable.Buffer[String]) => T the block function allows accumulation of each line in the Csv into the type T the block function recieves the T accumulator for each row in the CSV and a set of columns as the second parameter. It processes the columns and returns a second row.
