Converted doxygen style comments to reStructuredText style in the files
found in Cura/cura/Model directory recursively using the script
dox_2_rst.py (provided in the Uranium repo). Comments were manually
checked and changed if needed.
Note: dox_2rst.py struggles with decorated functions.
It's a quality container, not a material container. This was a copy-paste mistake.
Also added that this may be a global quality container, not always a per-extruder quality container.
Found during testing & tooling.
Previously it would use the material type from the material, but since
the material from the node can be different to that of the quality, we need
to use the one from quality instead (This is due to the fallback system)

You can now be assured that there is ALWAYS at least one child node, except for child nodes of intent profiles which don't exist.
Contributes to issue CURA-6600.
Among the machines, variants, materials, qualities and intents, only machines and materials can ever be added during runtime. For the rest, we don't need to listen to these signals.
