ver 0.5.0 snapshot
这是一版改动颇大的版本
- 引入了一个C#的公共类库，其中抽取了本人过去所写的部分工具性代码
- 在AppService内部增加了独立的后台线程支持，这是通过scheduler包含的。scheduler内含一个thread，并且支持多个子任务。这一代码实现有一点点复杂，因为是源自一些实际工程的代码。最简单的版本是无需支持子任务、无需scheduler，只要1个thread。
- 更新了界面逻辑，使之支持动态更新数据。
- 启用了内部cache做数据缓冲。
- 启用了一个demo task以随机数方式生成数据
- 更新了服务层的接口，使之更适合一个真实project的需要。特别是本着精简UI层代码的大原则进行。
- 更新了Test window的处理逻辑，使其能够多次reopen
