RazorEngine temporary files deletion using proxy domain.

From the RazorEngine Github page,

RazorEngine tries hard to delete the temporary files it creates, but this is not always possible. This is especially true if you run RazorEngine from the default AppDomain. RazorEngine will warn you in this situation by writing to the stderr.

The given solution works for console application. It unloads the proxy Appdomain when exiting the main. This approach won't work if the program is run as a Windows services.

MarshalByRefObject is used to access to objects across application domain boundaries.
