def movOneStep(milModClass, pinHighLow) : Moving single stepper motors
milModClass : module instance
pinHighLow : Signal pattern like [1,1,0,0]

def movTwinOneStep(milModClass1, pinHighLow1, milModClass2, pinHighLow2) : Moving twin stepper motors
milModClass1 : module instance
pinHighLow1 : Signal pattern
milModClass2 : module instance
pinHighLow2 : Signal pattern

example:
mod0.connect()
mod1.secondConnect()
StepUni.movTwinOneStep(mod0, [1,0,0,0], mod1, [1,0,0,0])
time.sleep(0.004)
StepUni.movTwinOneStep(mod0, [1,1,0,0], mod1, [1,1,0,0])
time.sleep(0.002)
StepUni.movTwinOneStep(mod0, [0,1,0,0], mod1, [0,1,0,0])
time.sleep(0.004)
