Previously it would just re-try all settings, but this really isn't needed (since
we have a setting relationship object that can tell us what settings depend on what).
This won't speed things up in a worst case scenario (since that will still be "caluclate
all the settings") but it will speed it up in most cases.
Most setting changes now only trigger a calculation that takes <0.2 sec isntead of the 1.1 sec.
Yes, those numbers seem big, but the error checking is already built in such a way that it spreads this
out over multiple frames (so it's not actually freezing that time, but it is doing shit it shouldn't do!)
CURA-7106
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.
