redeme好像没有更新

BuildContext buildContext = new BuildContext(); 应为 BuildContext buildContext = new SimpleBuildContext();

高级技巧中： public class MyBuildContext extends BuildContext 应是 public class MyBuildContext extends SimpleBuildContext

构建器ModelBuilder的使用说明貌似不可用，应该是版本升级后，文档及 test case 也没有同步更新，目前已经找不到正确的构建方式了。

有时间的话，麻烦更新一下呗

testcase应该更新了，readme还没更新，晚些时候我更新下。

天船老师，我准备在新公司推广该组件，readme应该还是老版本吧，现在应该变成类似这样的吧 另外问一下，你们也在用这个1.1.1版本吗？
