Added keyword arguments to createConstraint.
Changed initial values for the pivod XYZ form 1 to 0.0.
Changed initial values for the axis Z form 1 to 0.0.
Delete the parsing for 4 parameters, because parsing only the X pivot is not necessary, also it was not working correctly (int instead of float).
