/**
 * Implements the "MECARD" address book entry format.
 *
 * Supported keys: N, SOUND, TEL, EMAIL, NOTE, ADR, BDAY, URL, plus ORG
 * Unsupported keys: TEL-AV, NICKNAME
 *
 * Except for TEL, multiple values for keys are also not supported;
 * the first one found takes precedence.
 *
 * Our understanding of the MECARD format is based on this document:

 * http://www.mobicode.org.tw/files/OMIA%20Mobile%20Bar%20Code%20Standard%20v3.2.1.doc
