Message:

(1) fix in ProtocolAsPanel? that correctly calculates Kappa for data taken with the Cerca detectors. In the Kappa calculation, the data is manually scaled, bypassing the normal "ADD" step where the 4x detector data is correctly renormalized. Added a flag to divide by 4 if ILL detector type found.

(2) lots of bits to try to accomodate 2D resolution smearing. Changes to the QxQy? output to have everything needed: Qz, sigX, sigY, and shadowing. So presumably, all of the information is in the reduced data, where it should be.

• added a 2D resolution calculation based on David Mildner's notes.
• added 2D quadrature calculation for smearing, and new structure definitions
