/**
* Helper class for redirecting output to stdout or file using command line switch.
*
* Using this class it is easy to provide a command line switch to the user
* to redirect output to a file.
*
* Examples:
* \code
* int main(int argc, char* argv[])
* {
* cxxtools::ArgOut out(argc, argv, 'o');
* out << "this is printed to std::cout or to a file when a file name with the -o option is passed" << std::endl;
* }
* \endcode
*
* \code
* int main(int argc, char* argv[])
* {
* cxxtools::ArgOut out(argc, argv);
* out << "this is printed to std::cout or to a file when a file name is passed as a parameter" << std::endl;
* }
* \endcode
