Obstools uses class Sun that no longer exists

[Xarthisius]

$ grep Sun obstools.py
from .coords import LatLongCoordinates,Sun,Moon
seqp = Sun(ra.sitedate).equatorialCoordinates()
from .coords import Sun,Moon
sun = Sun()

Thanks for noticing this - the nightPlot and yearPlot functions are currently not working because the coords module is undergoing a big refactoring, and those functions have not yet been updated to reflect the new scheme. If you want to see what a working version was like, you can look back at commit 426d283 to see it while it was still working, and hence hopefully what it will look like when working again...

I'll mark this as fixed once that refactor is done and the nightPlot and yearPlot functions are updated to reflect that.

Note that astropy now has functionality to do this kind of stuff (see this example for how to use it)
