Nes2DMC 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.

see also [Nes2Triangle], [Nes2Square], [Nes2Noise]

*ar(trig, loop, freq)

trig - control or audio rate trigger

loop - looping off or on 0/1

freq - frequency 0-15

note that all functionality is not implemented, but it can still be somewhat (mis)used.
