working just need definition added for 'criteria line'

I know the other plots make their series config objects via a function, but that's because all the plot constructors make two nearly-identical series under the hood; one for the most recent water years' data, and one for the other years' data.

You do not need to make two series configs so you can simplify things by cutting out that function man in the middle:
```
var criteriaLineSeries = {
+                label: constituentName,
+                data: [[nar.fullReport.PlotUtils.YEAR_NINETEEN_HUNDRED,criteriaLineValue],
+                       [nar.fullReport.PlotUtils.ONE_YEAR_IN_THE_FUTURE,criteriaLineValue]],
+                lines: {
+                    show: true,
+                    fillColor: criteriaLineColor,
+                    lineWidth: 1
+                },
+                shadowSize: 0
+            };
+        };
```

Don't worry, other people creating plots in NAR are running into this too: https://github.com/USGS-CIDA/nar_ui/pull/178#discussion_r16447383
