/**
* Consumes output from a Command.
* This is useful when running commands that produce a lot of output, and you want to process it in a
* stream-like fashion.
* See CommandRunner.run( Consumer, Consumer ).
* <p>
* For commands which produce little output, it is simpler to use CommandRunner.collect() which
* consumes the output, and places it all into a String. See CommandResult.out and CommandResult.err.
* <p>
* If you don't care about the output at all, then you could use CommandRunner.run().
* In which case, any output is streamed to the existing stdout/stderr of the calling process.
