/**
 * Denotes name and value parts of a multi-part request
 * 
 * Values of the map on which this annotation exists will be processed in one of three ways:
 * 

 * If the type implements {@link retrofit.mime.TypedOutput TypedOutput} the headers and
 * body will be used directly.
 * If the type is {@link String} the value will also be used directly with a {@code text/plain}
 * content type.
 * Other object types will be converted to an appropriate representation by calling {@link
 * retrofit.converter.Converter#toBody(Object)}.
