QQ plot will fail if distribution goes over the periodicity range

[IAlibay]

One way to fix this in the short term is to look at the range in the values and see if they exceed 180 degrees, then shift all values accordingly.

This might be an issue for the mean, so it will have to be treated accordingly.

For now, visual inspection will show whether or not the distribution is close to uniform.

864c559 sort-of fixes this. It's not great and probably not fully statistically correct, but it's better than what it was.

Ideally we need to start looking handling circularity directly within the QQ code.
