See the docs.
Test data is in Matlab .mat format and generated here
but is stored in the ``euphonic_sqw_models`` repository.
In case the code changes so as to invalidate the test data, you can
generate it using runtests('test/EuphonicGenerateTestData.m') here.
Then copy the *.mat files in test/expected_output to the
euphonic_sqw_models repository and commit it.
Since we include euphonic_sqw_models as a submodule here, it will then
include the test data which must be the same in both repository.
The minimum require version of Euphonic is stored in the
min_requirements.txt file of euphonic_sqw_models (not here).
Like the test data, this is inherited by this repo as a submodule
and propagated further.
