Initial server-side CSAT for pepsi data.

csatTemplate(input, output, session, ddat, fdat, color_cutoff,
  columns = c(flavor_col, quality_col, likeme_col, preferother_col),
  gaugeTitles = c("Flavor", "Quality", "Like Me", "Prefer another"),
  minRange = 1, maxRange = 5, reversed = FALSE)

`input`	Required for shiny modules' server functions.
`output`	Required for shiny modules' server functions.
`session`	Required for shiny modules' server functions.
`ddat`	dataframe, data filtered by demographic variables.
`fdat`	dataframe, data filtered by demographic and product variables.
`color_cutoff`	vector, numerics defining cutoffs between different colours for the gauges.
`columns`	vector numerics, column numbers denoting pcols for each plot.
`gaugeTitles`	vector, titles for each plot (strings)
`minRange`	numeric, gauges' minimum value.
`maxRange`	numeric, gauges' maximum value.
`reversed`	logical, denotes whether gauge colours should be reversed (ie. warning colour for high values, happy colour for low values).
