* Initial fwd and inv w/ tests

* Add A-matrix and mueller-from-projection functions

* Debug AR_mueller

* Add convenience functions

* Make 4d transposes nd with moveaxis

* Add documentation

* Improve module docstring

* Change `KeyError` to `ValueError`

* Improved docs

* Remove unnecessary test

* Removed "float" from docs

* Revert "Removed "float" from docs"

This reverts commit d9dd7e3.

* Use `assert_almost_equal`

* fixed couple of  typos

* `A` -> `I2S` & new `S2I`

* comprehensive renaming

* copy `s0` <-> `tra`

* `np.array(s0)` so that it always has `.copy()`

* Set default to "inverse"

* Add .git-blame-ignore-revs (#109)

* Add #110 pr doc

* black formatting

* move 2D-to-3D phase recon to phase.py

* convert gen_HZ_stack to ZYX

* keep existing gpu handling

* add 3D_to_3D phase OTF

* improve naming consistency in phase_2D_to_3D_OTF

* Add kwargs to recon params

* change axes for 2D recon preparation

* simplify 2D_to_3D recon with kwargs

* handle padding and simplify OTFs

* add 3D_to_3D recon with kwargs

* temporarily remove docs for rewriting

* first dependence on torch

* move gen_Hz_stack to torch

* convert 2d wotf to torch

* move gen_Greens_function_z to torch

* move important utils to torch

* phase3Dto3D complete overhaul

* refactor

* optics.py to torch

* high-level tests

* splitt phase.py into models

* clean up 3D script

* cleaning and notes

* phase2Dto3D placeholders

* clean tests

* use napari in tests

* better skipping

* reduce dependencies

* update tests

* maintiain PTI simulation's compatibility revised optics functions

* drop pdb

* Preserve birefringence recon

* fix transpose bug

* transpose bug

* phase2Dto3D.py example

* support padding

* empty model for planaraniso

* improved names

* broad renaming of phase2D_3D and phase3D_3D

* updated 2D phase and absorption recon

Return the 2D absorption along with phase. Viewing OTFs in napari is very nice. I changed the axis order to be able to compare phase and absorption OTFs at focal plane.

* display OTFs with Z-axis as a slider

* changes to 2D phase/absorption simulation

I suggest changing this example to be simulation and reconstruction of 2D specimens, thinner than the depth of field of the microscope.

* rename models to <object-type>_<object-thickness>_<data_shape>

* fix isotropic_thin_3d example, include absorption

* 2D -> 2d, 3D -> 3d
