+/**
+ * Compound property.
+ *
+ * This class adds (de)serialization of compound properties to/from arrays.
+ *
+ * Currently the following properties from RFC 6350 are mapped to use this
+ * class:
+ *
+ *  N:          Section 6.2.2
+ *  ADR:        Section 6.3.1
+ *  ORG:        Section 6.6.4
+ *  CATEGORIES: Section 6.7.1
+ *
+ * In order to use this correctly, you must call setParts and getParts to
+ * retrieve and modify dates respectively.
