UJO Framework为对象提供了一种有别于JavaBeans的架构。
改进内容：
1. The method UjoProperty.getValue() replaces the value of null as
the default, instead of the original method Ujo.readValue() in the
previous release.
2. Two UjoProperties can be easily... concatenated using the new type safe method add(...).
3. The base UJO objects support the 'java.io.Serializable' feature, including the OrmTable.
4. There is code cleanup, extended JavaDocs, and small bugfixes
