Rpc Call Proxy

When communicate with Another System , for some reason need to :

1. log the time (calling time , etc)

2.Exception handling 

This is a RPC caller which handles exception in each call 

/// <summary>
    /// Remote Procedure Call Proxy 
    /// Add log(timeline,etc) before/after RPC 
    /// Handle Remoting Call Exception 
    /// </summary>
