  29  * vCard parser for vCard 2.1. See the specification for more detail about the spec itself.
  30  * </p>
  31  * <p>
  32  * The spec is written in 1996, and currently various types of "vCard 2.1" exist.
  33  * To handle real the world vCard formats appropriately and effectively, this class does not
  34  * obey with strict vCard 2.1.
  35  * In stead, not only vCard spec but also real world vCard is considered.
  36  * </p>
  37  * e.g. A lot of devices and softwares let vCard importer/exporter to use
  38  * the PNG format to determine the type of image, while it is not allowed in
  39  * the original specification. As of 2010, we can see even the FLV format
  40  * (possible in Japanese mobile phones).
