Message:

renamed white beam smearing models so they would be grouped together on the file list.

Re-worked the logic and flow of the averaging/plotting/saving steps of the reduction protocol so that it would flow cleanly and leave room for changes for the multitude of different collimation conditions. The averaging routines are now aware of the collimation conditions so that the appropriate resolution can be calculated. The collimation string is also written out to the averaged data file as element[9] of the protocol. The hope is that one could key on this collimation string to decide how to proceed with the analysis.
