-  Macros CONSOLE, CONSOLE_WARN, CONSOLE_ERROR are used for Console output
-  CONSOLE_WAIT waits for user to hit Enter
-  In order to see Console output macro USE_CONSOLE should be defined before Console.h is included.
-  Since Console.h is added in PluginStdAfx.h, then 2 ways to log in Console ouput:
-  1. Uncomment "#define USE_CONSOLE" in PluginStdAfx.h - Console ouput will be available in all files.
-  2. Add "#define USE_CONSOLE" as very first line of a cpp file - Console ouput will be available in this file
