Added
- Correction of bug pointing to throughputs for wrong order when calculating LD coefficients.
- Switch default stellar models to 3D grid for LD calculation.
- Simplify LD coefficient calculation.
- Misc. bug fixes.

Removed
- Unnecessary functionality to calculate LD coefficients on grid of stellar models to derive errors.

Added
- Add time-domain jump detection for ngroup=2 observations.
- Allow for integration-level correction of 1/f noise.
- Paralellization of stability parameter calculations.
- Allow for piecewise subtraction of background.

Added
- Updated run_DMS script to accept yaml config file.
- TracingStep can now calculate changes in x and y position of the trace as well as the FWHM.
- BackgroundStep has been moved to Stage 2.
- Background is re-added after 1/f noise correction during Stage 1 such that it is properly treated by the non-linearity correction.
- Speed improvements for 1/f and hot pixel corrections.
- stage4.py: code including routines for light curve binning and parallelized fitting using ray and juliet (transit only currently).
- fit_lightcurves.py: script to fit spectrophotometric light curves.
- fit_lightcurves.yaml: config file for fit_lightcurves.py.

Removed
- Redundant plotting routines.
- Multiple depreciated utility functions.

Added
- Base prerelease code for Stages 1 - 3.
