Hello,

please consider my changes to the Stepper library (see attachments).
Main features of this version:

1. 100% compatible with the actual master branch
2. generic driver support (see example stepper_oneRevolution_ULN2003 for driver ULN2003ERP & Motor_BYJ48)
3. constructors harmonization by introducing the initMotor method,
4. speed and size optimization of method stepMotor by introducing the phasesMatrix array

Thank you in advance,
Stanislav Kniazev
