jamescasbon/PyVCF — Issue #26: Prevent cmp on list values in Call data

If I have a list of values, say AD=10,12 and in some downstream code I say:

```
if call.data['AD'] > 10:
do_something()
```

Then I get unknown behaviour since python implements comparisons for all basic types. I want this to raise an exception so that I know my filter is bad.

This will be much worse since we fixed #19. Previously all values were lists. Now some are lists and some are not.
