JSefa (Java Simple exchange format api) is a simple library for stream-based serialization of java objects to XML, CSV, FLR or any other format and back again using an iterator-style interface independent of the serialization format. The mapping between java object types and types of the serialization format (e. g. xml complex element types) can be defined either by annotating the java classes or programmatically using a simple API. The current implementation supports XML, CSV and FLR - for XML it is based on JSR 173.

 * Iterator-style interface for stream based CSV serializer.
 * 
 * Note on handling of null values:

 * 1. null values of simple types (e.g. String or Date) will be
 * serialized to an empty string (default) or the String explicitly configured as the null value string (see
 * {@link CsvConfiguration#setDefaultNoValueString(String)}).

 * 2. null values of complex types (classes annotated with CsvDataType) will be
 * serialized to a sequence of empty CSV fields (e. g. ';;;;;').
