 * MVVMFrame 框架基于Google官方的 JetPack 构建，在使用MVVMFrame时，需遵循一些规范：

 * 如果您继承使用了BaseModel或其子类，你需要参照如下方式在构造函数上添加@Inject注解
 *
 * @example BaseModel
 * //-------------------------
 *    public class YourModel extends BaseModel {
 *        @Inject
 *        public BaseModel(IDataRepository dataRepository){
 *            super(dataRepository);

 * //-------------------------
 *

 * 标准MVVM模式中的M (Model)层基类
