Module Csv_writer

* Compliant simple CSV writter. * * This library is designed to deal with proper CSV (no quotes allowed in the * middle of the fields...). It is fast and flexible: by splitting most * writing functions in two parts one that gives the length of the string to * write and another that writes the result in a subpart of another string we * avoid unnecessary string creations.
