PDFgetN workflow algorithm is implemented.

I ran two scripts in parallel to compare the results from SNSPowderReduction and PDToPDFgetN.  There is slightly difference, but acceptable.  

Issue is thus closed.

Engg: improved 'plot focused data'

As far as the validation goes this PR fixes the problems. However, When plotting I found that once you have removed background in the range 65000-75000 for example, if you try to adjust the range (65000-65001 for example) then the plot is not updated and the background associated with the previous range will be plotted instead. I would say make a separate issue for this as it is beyond the scope of this one.
