This program will calculate the area moment of inertia about
the zz axis (through the centroid as indicated), Izz,
and the area of an I-beam given the dimensions of the beam.

<- width -> -
Hopefully that is an informative diagram! Note that the height
goes all the way from the bottom to the top of the beam, not from
inside the flanges.
