 * The HTTP multipart POST method is defined in section 3.3 of

 * <blockquote>
 * The media-type multipart/form-data follows the rules of all multipart
 * MIME data streams as outlined in RFC 1521. The multipart/form-data contains 
 * a series of parts. Each part is expected to contain a content-disposition 
 * header where the value is "form-data" and a name attribute specifies 
 * the field name within the form, e.g., 'content-disposition: form-data; 
 * name="xxxxx"', where xxxxx is the field name corresponding to that field.
 * Field names originally in non-ASCII character sets may be encoded using 
 * the method outlined in RFC 1522.
 * </blockquote>
 * </p>
 * <p>This entity is designed to be used in conjunction with the 
 * {@link org.apache.http.HttpRequest} to provide
 * multipart posts.  Example usage:</p>
