• add self tests
• give better user feedback when a library is missing or not working

• gemini.bin command line now has only one mandatory argument: the top-level output directory. The inputs/config.nml should already be in there when gemini.bin is run.
• if the user doesn't specify an output file_format, Gemini.bin will use the same file format as the input/simsize.*.
• Check for NaNs and impossible values in several more places.
• correct potential source calculation error
• eliminate stack overflow in tests by using allocate()
• allow non-MPI unit tests to build even without MPI
• auto-download and auto-setup PyGemini if needed
• eliminate duplicative specification of "flags" in config.nml. Use presence of namelists to determine if an input is desired.
• allow namelists to be read in a different order than in file
• move all Python scripts to PyGemini except for bare minimum used for self-tests
• add optional EIA namelist
• make several .f90 files generated to cut down on linking for minimal parameters (faster parallel builds)
• add -dryrun to CI
• update reference data URL

• add gemini.bin -dryrun used by job.py to help avoid HPC queuing for simple errors on first time step
• Make job.py / plasma.py build msis_setup more reliably
• cleanup python packaging
• remove needless file copying from Fortran

set safe defaults for NML flags. Under certain conditions they could default non-zero otherwise and cause simulation to hang early just after first time step.

remove unneeded code from job.py

job.py: allow manual specify max cpu count, handy for HPC where you be submitting to different node.

Fixed a bug where MPI image count was incorrect on some systems, and added test to mpi_basic to check for this.

add implicit none (type, external) for robustness

• general code quality via use of Fortran 2018 implicit none (external)
• fix bug where on some systems h5fortran / nc4fortran / hdf5 / netcdf4 would falsely not be found
• remove many preprocessed files instead using configure_file generated Fortran source for clarity
• make msis_setup more robust to use from external Python / Matlab programs
• do compiler/library checks with clearer failure messages
• add more feature printouts to final summary to help users understand their configuration

• CMake: enhancements to make CDash and console output prettier
• Docs: split Readme into several linked files and update to current info
• grid: enhance grid_check. Still need to make checks stronger for manual MPI count specification #17
• use gemini_cfg for more parameters
• general code quality and lint

• add CDash
• add NetCDF4 option, by default off, while HDF5 is default on
• improve Gemini.bin CLI to be flag-based
• fix memory leak in vendor/lapack95 that would silently crash larger sims with SIGKILL 9
• fix GCC 9.3.0 by removing redundant use

• allow raw, hdf5, netcdf file IO without recompile
• make MSIS-Python interface use stdin/stdout pipes instead of files
• enable Fortran HDF5 write compression automatic
• NetCDF is not yet fully working, needs to be debugged, but it's mostly implemented.
• move Matlab, archive to own repos
• add h5diff-based test--in case Python numeric libraries are messed up, h5diff is standalone test.
