Rayoptics

==============

Interpret Zemax .zmx files as having UTF-16 encoding, with a fallback to UTF-8. Push classes in :mod:`~.seq.medium` towards a common set of queries with :mod:`opticalglass` glass and catalog classes. Add :func:`~.raytr.analyses.trace_list_of_rays` specified by starting point, direction cosines and wavelength.

==============

Add import of Zemax .zmx files. Demonstrate access to lens-designs.com collection of zemax files and use that to test import capability. Build a strong tie with :mod:`opticalglass` package, including drag and drop from a glassmap view to the layout, yybar and lens table views. Add x, y-toroids. Add a paraxial-based set vig calculation to Tools menu. Set up a protocol for aperture checking in the ray trace. Add conda installation via conda-forge.

==============

Refactor/repackage the :mod:`~.optical` subpackage into more manageable chunks. New subpackages include :mod:`~.seq`, :mod:`~.raytr`, :mod:`~.parax`, :mod:`~.elem` and :mod:`~.oprops`. The :mod:`~.layout` and :mod:`~.diagram` modules were moved from the :mod:`~.gui` subpackage to the :mod:`~.elem` and :mod:`~.parax` subpackages, respectively. The refactoring broke reading of existing .roa files; a preprocessing step was added in the :mod:`~.roafile` module to handle mapping the old structure to the new one. Documentation and Jupyter notebooks were updated to reflect the changes.

==============

Misc bug fixes and improvements: draw mirror substrates consistently, old .roa files should be resaved. Consolidate InteractiveFigure color and lw control in dicts, and retrofit layout usage to match diagrams.

==============

Add single field monochromatic PSF calc and display. Add dashboards for jupyter notebook usage for refocusing, etc. Revisions to app manager protocols for wider usage, esp. including matplotlib Figures. Use brute force OPD calc instead of equally inclined chords until eic behavior with decentered systems is fixed.

==============

Add add_from_file() method to OpticalModel to enable importing pieces of optical
models to a master model. Include a Jupyter notebook demonstration.
