Modified phase table in stepper.cpp to enable stepping a bipolar motor using a twin H-bridge driver.
Fork of
stepper

Kenji Arai
Corrected single-stepping, now walking up or down just one phase table. Compile-time options for driving bipolar motor in any of single-phase, two-phase, or half-stepping. Coils remain engaged at end of specifed movement command - de-energize coils by issuing a motor.move(0) while already stopped.

| 4:5b596b405573 | 2014-12-21 | gregeric | Allow sequential single-stepping (keep record of phase).; Walk up or down one phase table to correctly single step either direction.; Motor in stop condition engages coils - release by issuing 0-step move while already stopped. |
