Create a CSV splitter

[ecourtial]

Create two CSV splitter class.
One splitting the CSV in n parts.
One splitting the CSV in n max lines.

Be careful with the multilines CSV.

Need documentation update.

Splitting in N parts is not really ETL friendly, how the Loader class can know how much lines will be Extracted and Transformed ?
Splitting according to N max lines is already possible with the current CsvLoader :)
