[Halld-tagger] Analysis of tagger field map at 0.75 T added

[Daniel Sober]

That is correct.  I have not yet implemented the calibration data in the 
plots.  I wanted to have a public record of the raw data, and I am still 
working on understanding the calibration and how it relates to the 
differences in the map.  This is the first week of classes, so I have 
been slowed down a bit, but will get there soon.
