motor: Support unimplemented acceleration and velocity
Closes #24 (closed)
BLISS CalcMotor
dont have acceleration nor velocity.
This patch fixes raised exception returned by such axis.
I use it right now in tomo fror XYOnRotation
controller.
BTW a CalcMotorController
can also implement such attributes (there is no such controller right now), so it could be valid values insteand of exception. This implementation handle that case.
