    Hi,  I have been working on reconciling the new mult code with the old.
    I was able to track down
    one significant difference in the two calculations to the approx. 2 cm
    difference found between the
    BB and TPM1 vertices.  In the "old" analysis, I had explicitly worked
    this into the vertex I
    (illegally) passed to the BrRdoModuleMult class.   However,
    putting such an artificial offset into the BrSiRdoMult and BrTileRdoTile
    classes (both of which need
    the vertex) is likely to cause consternation in the future.
    
    Is there a reason why this offset is not incorporated in the vertex
    returned by the BrRdoBB module?
    
    For the moment, I have updated the mult modules to incorporate the
    vertex offset.  There are still
    differences between the si and tile energies reported by the "old" and
    "new" code  for which I have
    not yet been able to identify causes.
