Nes2Square wrapper class for the Nes2 UGen

requires my BitOr plugin.  available at http://www.fredrikolofsson.com/pages/code-sc.html

simplifies the interface for the [Nes2] ugen a little.  provides standard ranges with clipping for all inputs.  no need to deal with bitwise register calculations, though note that this class is a bit less cpu efficient than to use the standard Nes2.
