Derived section properties

Integrated from the section's own outline including the root and toe radii, whose arcs are integrated analytically rather than approximated by facets. For 45 x 45 x 6 EA the computed area agrees with the published value to 0.10% and Ix to 0.02%. Where a value is also published, the published one above is the one to quote.
