 * If you call read() in \phpseclib3\Net\SSH2 you may get {@link http://en.wikipedia.org/wiki/ANSI_escape_code ANSI escape codes} back.
 * They'd look like chr(0x1B) . '[00m' or whatever (0x1B = ESC).  They tell a
 * {@link http://en.wikipedia.org/wiki/Terminal_emulator terminal emulator} how to format the characters, what
 * color to display them in, etc. \phpseclib3\File\ANSI is a {@link http://en.wikipedia.org/wiki/VT100 VT100} terminal emulator.
