+Material Library for HVAC Load Calculator
+Updated 2025-05-17: Added all materials and constructions from ASHRAE_2005_HOF_Materials.idf.
+Updated 2025-05-16: Removed mass_per_meter, added thermal_mass method, updated CSV handling.
+Updated 2025-05-16: Fixed U-value calculation in Material.get_u_value.
+Updated 2025-05-16: Updated MaterialCategory to Finishing Materials, Structural Materials, Sub-Structural Materials, Insulation.
+Updated 2025-05-16: Fixed Construction.get_thermal_mass to use avg_specific_heat.
