Install wheel package in Gitlab CI
Description
Several of the dependencies get installed from source, and the CI log shows messages like this:
Using legacy 'setup.py install' for iCalibrationDB, since package 'wheel' is not installed.Having the wheel package available should mean pip builds & caches a wheel. The CI runners appear to have a persistent cache directory, so this should speed up CI a little bit once those wheels have been created.
I also fixed a docstring I was looking at, which should have no effect on either the CI or the code.
How Has This Been Tested?
CI will run when I open this MR.
