Overview

In some cases, there is the need to redirect standard output to a string. In general class StIO will do it without any problem. However, when integrating with some libraries, for instace, Renjin, Renjin standard output and Ruby standard output are different, so we need to redirect both standard outputs to the same string. The integrating library will have to implement methods set_std_out, set_std_err, set_default_std_out and set_default_std_err.
