Versioning of images #3
Description
Changing the IDs in the tutorial might have some bad consequences, when older versions of FlexMeasures produce different ones than the tutorial or the pictures show them.
Actually, the docs are versioned, but: older versions of the docs will also use these pictures.
In principle, we could create tags in this repo which match the versions of FlexMeasures, so we could make our docs reference the version of a screenshot which will alwys match the docs version.
