duplicate values in reduced data

Description
Need to be sure that duplicated q-values do not appear in reduced I(q) data sets. This can cause errors in fitting, or fatal errors in desmearing of USANS data.
Try to identify and remove these duplicated points.
VCALC data is a likely problem since it's "perfect" and L/R or T/B pixels will have identical q-values from a perfect center. Offseting the the perfect center could alleviate this.

I have not seen this problem arise any longer. There is a function (added more than a year ago) to remove duplicates from the I(q) sets by averaging values that are within a low tolerance ( q< 0.01 % different, I think?)
so I'm closing this for now
