/**
* @ingroup console
*
* A manipulator for gout essentially meant to facilitate a C++ iostream
* version of mlprintf. Using moveTo in the gout stream (and ONLY gout),
* will set the stream to display the next line-buffered text using an
* mlprintf rather than a normal mprintf. gout needs to be acquired if other
* threads might write to gout. The following code:
*
* <code>gout << acquire << moveTo(10, 15) << "Hello, World!" << flush << release;</code>
*
* works like <code>mlprintf(10, 15, "Hello, World!");</code>. Other stuff
* may be before if anything is in the stream -- remember gout only displays
* when it encounters a newline or is explicitly flushed.
*
* The position 0,0 is the upper left corner of the console.
