+/*all this header does is to globally overwrite "operator new" to give some more detailed error messages and write memory dumps
+Usage:
+	 - Include everywhere before any other file: $(ProjectDir)\shared\debugNew.h
+	 For Minidumps:
+	 - Compile "debugNew.cpp"
+	 - Include library "Dbghelp.lib"
+	 - Compile in Debug build (need Symbols and less restrictive Optimization)
