Create Primary Plot Will create and configure gsPlot object using provided data

createPrimaryPlot(uvInfo, refInfo, compInfo, comparisonStation,
  primarySeriesList, dailyValues, meas_Q, water_qual, gw_level, readings,
  approvals, corrections, ratingShifts, isDischarge, timezone,
  excludeZeroNegativeFlag)

`uvInfo`	main timeseries information for the plot
`refInfo`	timeseries information for reference series
`compInfo`	timeseries information for comparios series
`comparisonStation`	station id where comparison info comes from
`primarySeriesList`	named list of timeseries to be plotted
`dailyValues`	named list of daily values (lists of points) to be plotted. Each name tells what approval level the DV is at.
`meas_Q`	Q measurement data to be plotted (list of points)
`water_qual`	wq measurement data to be plotted (list of points)
`gw_level`	ground water level measurements data to be plotted (list of points)
`readings`	named list of different readings series (ref/csg/hwm readings)
`approvals`	bars to be plotted which show approval level of data
`corrections`	data correction information be plotted (time/correction pairs)
`ratingShifts`	rating shift information to be plotted
`isDischarge`	true if the plot has discharge as it's main corrected series
`timezone`	timezone to plot/display in
`excludeZeroNegativeFlag`	flag to exclude ploting of values <= 0
