## A MaterialGroup represents a group of material InstanceContainers that are derived from a single material profile.
# The main InstanceContainer which has the ID of the material profile file name is called the "root_material". For
# example: "generic_abs" is the root material (ID) of "generic_abs_ultimaker3" and "generic_abs_ultimaker3_AA_0.4",
# and "generic_abs_ultimaker3" and "generic_abs_ultimaker3_AA_0.4" are derived materials of "generic_abs".
#
# Using "generic_abs" as an example, the MaterialGroup for "generic_abs" will contain the following information:
# - name: "generic_abs", root_material_id
# - root_material_node: MaterialNode of "generic_abs"
# - derived_material_node_list: A list of MaterialNodes that are derived from "generic_abs",
# so "generic_abs_ultimaker3", "generic_abs_ultimaker3_AA_0.4", etc.
