New BBI

the BBI equation is:

\frac{\frac{{(M O R)}^{2}}{M O E} - \frac{D e n s i t y}{0.65} + 500}{600}

MOR (MPa) | MOE (GPa) | Density (Kg/m^3)

don't use this equation to make a list it should always be graphed in 2D versus elasticity

0.65 | 500 | 600 are adjustment values to lessen reading bias as one could try to compare woods at different MOE, and a 0 to 1 scale is nice.
