/**
 * Material Extractor
 *
 * Extracts IFC material definitions and associations.
 *
 * Material concepts in IFC:
 * - IfcMaterial: Basic material (concrete, steel, wood, etc.)
 * - IfcMaterialLayer: Material with thickness (e.g., in walls)
 * - IfcMaterialLayerSet: Set of layers (e.g., multi-layer wall)
 * - IfcMaterialProfile: Material with profile shape
 * - IfcMaterialProfileSet: Set of profiles (e.g., structural members)
 * - IfcMaterialConstituent: Material as part of a composite
 * - IfcMaterialConstituentSet: Set of constituents
 * - IfcRelAssociatesMaterial: Associates materials with elements
