This will make the changes easier, in case the repository is named differently.
Then one only needs to change the path in register_classes.py.

Now the gain of the input set for a PID is considered, such that the set value is the physical voltage that goes into the ADwin.
For that I also changed how we keep track of the AIn of PID channel index for the module arrays (moved storage from Attributes in devices to connection_table_properties).
