      sqlite 局域网远程访问
      远程代理 是基于 WSCF (WebSocket Communication Foundation) 建立的
      WSCF 项目：http://private.flyautomation.net:82/panruising/wscf.git
      ## RemoteSQLite
      **项目主体**
      ISQLiteRemoteService *SQLite服务代理*<br/>
      ISysTimeService *系统时间*<br/>
      ## SQLiteRemoteServerUI
      **SQLite服务代理**
      <br/>
      SQLiteRemoteServerUI 只是 RemoteSQLite.RemoteSQLiteServer 的外壳。<br/>
      使用方法：<br/>
      放在 ###.sqlite3 文件 那台电脑上运行。 <br/>
      <br/>
      它提供2个服务<br/>
      /SQLiteRemote *SQLite操作*
      1. ExecuteReader
      2. ExecuteNonQuery
      3. ExecuteScalar
      /SysTime *系统时间操作*
      1. Now
      2. SetTime *通过网络延时比较准确设置时间*
      3. GetTime
      ## SQLiteRemoteClientUI
      **SQLiteRemoteServiceClient 的测试**
