-  Stepper.cpp - - Stepper library for Wiring/Arduino - Version 0.4
-  
-  Original library     (0.1) by Tom Igoe.
-  Two-wire modifications   (0.2) by Sebastian Gassner
-  Combination version   (0.3) by Tom Igoe and David Mellis
-  Bug fix for four-wire   (0.4) by Tom Igoe, bug fix from Noah Shibley  
-
-  Drives a unipolar or bipolar stepper motor using  2 wires or 4 wires
-
-  When wiring multiple stepper motors to a microcontroller,
-  you quickly run out of output pins, with each motor requiring 4 connections. 
-
-  By making use of the fact that at any time two of the four motor
-  coils are the inverse  of the other two, the number of
-  control connections can be reduced from 4 to 2. 
-
-  A slightly modified circuit around a Darlington transistor array or an L293 H-bridge
-  connects to only 2 microcontroler pins, inverts the signals received,
-  and delivers the 4 (2 plus 2 inverted ones) output signals required
-  for driving a stepper motor.
-
-  The sequence of control signals for 4 control wires is as follows:
-
-  Step C0 C1 C2 C3
-     1  1  0  1  0
-     2  0  1  1  0
-     3  0  1  0  1
-     4  1  0  0  1
-
-  The sequence of controls signals for 2 control wires is as follows
-  (columns C1 and C2 from above):
-
-  Step C0 C1
-     1  0  1
-     2  1  1
-     3  1  0
-     4  0  0
-
