Updates to DEF-files and onlineGUI for HMS DC wire efficiency

In THcDC.cxx the method EfficiencyPerWire is called
which for the Golden track calculates which wire in each plane
"should" have been hit ( fills wirenumber in H.dc.wireHitShould[planenum]
and also calculates which wire "did" get hit by the track ( fills
wirenumber in H.dc.wireHitDid[planenum]) .

As an example of HMS histograms was created in
DEF-files/HMS/PRODUCTION/DC/hdc_eff_histos.def
which creates two sets of histograms for each plane
of the "should" and "did" wire numbers.

Updated hstackana_production.def to include
hdc_eff_histos.def and a newly created TEST_STANDS/DC/hdc_resid.def

For onlineGUI create UTIL/GEN/dcwire_efficiency.C for taking
ratio of the "did" and "should" histograms
and as exmaple HMS/TEST_STANDS/DC/hdc_wireeff.cfg for plotting
the histograms.
