 A multi-dialect CSV parser written in Swift for importing and exporting the delectable flavors of comma separated values documents. This library implements [Frictionless Data's CSV Dialect](https://frictionlessdata.io/specs/csv-dialect/) spec which acknowledges that the CSV RFC 4180 is retroactive and that in practice numerous flavors of documents and exporters exist. The library also supports streaming of data incrementally for a low peak memory footprint.
