Error when reading calibration info

[kosalk]

When trying to read the calibration info with calibration.get_info(), an error is raised AttributeError: 'Calibration' object has no attribute 'model_name'.

In Calibration.py (line 42 to 48), the attributes should be taken from info and not self.

Hello,

thanks for pointing this mistake out. I fixed it in the wrapper implementation.
