# MaterialManager maintains a number of maps and trees for material lookup.
# The models GUI and QML use are now only dependent on the MaterialManager. That means as long as the data in
# MaterialManager gets updated correctly, the GUI models should be updated correctly too, and the same goes for GUI.
#
# For now, updating the lookup maps and trees here is very simple: we discard the old data completely and recreate them
# again. This means the update is exactly the same as initialization. There are performance concerns about this approach
# but so far the creation of the tables and maps is very fast and there is no noticeable slowness, we keep it like this
# because it's simple.
