cxxtools::posix::CommandOutput starts a process and the stdout of the process can be read.
The class is derived from std::istream, so all methods provided from that
base class can be used to read the output.
Typical usage example:
\code
cxxtools::posix::CommandOutput ls("ls");
ls.push_back("-l"); // add a parameter
ls.push_back("/bin"); // and another one
ls.run(); // start the process
// read output line by line
std::string line;
while (std::getline(ls, line))
std::cout << line << std::endl;
\endcode
