Subject: Basic sky rendering using the model by Nishita et al.

See "Display of the earth taking into account atmospheric scattering" (Nishita et al., 1993)

`bluedot.py` renders the full earth disk while rotating the sun around it.

`sunrise.py` renders the rise of the sun.

Physical model constants may be changed in `planets.py`.
