I want to creat ea BaseViewController with the basic functionality for the viewer. This will be inherited by the CameraViewController and the MIPViewController. Hopefully this avoids code duplication.

Still a bit chaotic. Lots of features that are only partially implemented in the original camera view. Trying to use inheritance to simply matters.

Also consolidate crosshair logic.

Set the channel appropriately.

```        channel_idx, _ = self.identify_channel_index_and_slice()
        self.image_metrics["Channel"].set(channel_idx + 1)```

cleanup the attributes. Proper initialization of attributes...

Clean up camera view controller attributes.

Removed some liabilities with the slider.

Currently, some of the logic in the __init__ is duplicated from the initialize method.

Time to test this on a real system. If it works, then I will add the lazy loader next...

Very close. Need to remove some duplicated code and clean out the last few bugs.

I think I am running into threading problems now...

...

Trying to make sure that all of the autoscaling, transpose, min/max widgets update accordingly in the slider view.

When I tried to do this, the update_min_max_counts function should call process_image, but that then calls update_min_max_counts again, causing a recursive error.

Tests are a mess.

@abc.abstractmethod forces child classes to have methods...
