My assessment of why IntegrationTest was failing was incorrect.  After perusing the history I found that in repository revision 599, I introduced changes to the computation of Transition volume which accounted for the volume of the shoulders as well as the body of the transition.  This change broke the computation of CG.  This commit reverts IntegrationTest and adds some cg tests to SymmetricComponentVolumeTest which contains the values produced by the old code.  A future commit will correct SymmetricComponent.getCG and all these tests will work again.
