 *
 * this class represents an cafeteria entry. An entry is part of the total 
 * cafeteria plan of one day. The entry serves as event, request and reply of
 * cafeteria information. <p>
 * In case of an request, only the <em>kind</em> field is necessary to be set. 
 * In case of an event or an reply the <em>kind</em> and <em>date</em> field
 * are obligatory. Other fields are optional depending on the kind of event or 
 * request.<p>
 * Example:
 * <pre>
 *     kind          = MAIN
 *     date          = 17.05.1999
 *     meal          = "Rahmschnitzel"
 *     soup          = "Kartoffelsuppe"
 *     supplementals = { "Spätzle", "Salat" }
 *     beverages     = null
 * </pre>
 *
 * It has to be serializable to be transmitted via a software bus (like iBus).
