testAlphaIIIStructure
    Three fins in finset, so Ixx and Iyy are reduced by a factor of 3
    Ixx reduced from 5.2771946530250825E-5 to 1.7590648843416942E-5
    Iyy reduced from 1.3580770106050167E-4 to 4.526923368683389E-5

    Total rocket MOI changed to Ir=1.8763734635622462E-5 and
    It=2.1238394331365588E-4

testFalcon9HComponentMOI
    Three fins in finset, so
    finset rotational MOI  changed from 0.00413298 to 0.001377661595723823
    finset longitudinal MOI changed from 0.01215133 to 0.004050443797127646

testFalcon9HeavyBoosterLaunchMOIs
    Two finsets, each three fins.  Each finset's MOI are reduced as in
    testFalcon9HComponentMOI, resulting in change to totals
    Ir=0.013480523485489424, It=0.07017476021288252

testFalcon9HeavyBoosterSpentMOIs
    Two finsets, each three fins, as above
    Ir=0.010420016485489425, It=0.06398514917026163
