clean-up #18
Description
A few things could be cleaned up/homogenized throughout the repo:
- in inversion.py: naming of "auxiliary_start", "timewindow_start", etc. could be more intuitively named.
- in evaluate.py: check the docstring for the likelihood calculation class
- in inversion.py and evaluate.py: both files define a to_days function, but they are different. hopefully only one is needed and can be used for both.
- update the README
