Check material database is accurate and convert to derived units from si_metric.ut

[wgbowley]

1. Check all materials are accurate
2. Convert from derived units to si_metric.ut units
3. Add more materials and include mechanical properties for mechanical solvers.

Begin making the derived unit section for the material library and perhaps a electrical component library to use.

Each material has these properties sections (order enforced):

• Physical
• Chemical
• Electrical
• Magnetic
• Thermal

Optional:

• grades (magnets)
• chemical
