```
Add AstroWaveNet model, a generative model of astronomical light curves. AstroWaveNet's hidden states can be used in a semi-supervised fashion for downstream tasks like finding exoplanets.

- Add the option to interpolate missing time values when reading Kepler light curves. · 259b7d1d
  Chris Shallue authored Aug 16, 2018
```
This applies mainly to scrambled data (NaN time values typically come with NaN flux values, which are removed anyway, but scrambing decouples NaN time values from NaN flux values).

- Remove `invert` option from kepler_io.read_kepler_light_curve(). · 025efbf3
  Chris Shallue authored Aug 03, 2018
```
Inversion should be done *after* fitting a normalization curve to the stellar variability and dividing it away. Doing it before normalizing may result in unintentionally reversing the inversion. Therefore we remove the option to do it at this point.

- Return additional metadata about the spline fit: likelihood_term, penalty_term, bic.
- Don't fit a spline to < 4 points. Previously, light curve segments with less than 4 points would be fit by a fake spline that fit the points exactly.
- Better support for light curve segments with 0-2 points.
