[FT][OT] Ship Classification Grid

http://www.projectrho.com/rocket/rocket3t.html#shipgrid
I'm fiddling around with using a triangular grid to
define various classes of warship.  I'm using
Weapon/Defenses/Movement for classification variables,
but I'm sure others could be used.

Once you see the method in my madness, you can see if
it is worth adapting to Full Thrust.
