/*

*** EXPERIMENTAL
 This drives the stepper PWM at high frequency.  This is quieter and works best for low 
 currents.  But it needs to be debugged, sol leave it commented out unless you're experimenting. 

 ***NOTE*** 
 If set, FAST_PWM changes the frequency of Timer 0 so that PWM on pins H1E and H2E goes at
 a very high frequency (64kHz see: 
 http://tzechienchu.typepad.com/tc_chus_point/2009/05/changing-pwm-frequency-on-the-arduino-diecimila.html)
 This will mess up timings in the delay() and similar functions; they will no longer work in
 milliseconds, but 64 times faster.
