Changes in version 0.6.1                        

  - Correct general calculations of water types
      - Allow water types to use Meas Alk if HCO3 is missing (identified
        by HCO3* in the returned water type).
      - Water type also returns a check column mission_ion to identify
        if the water type is missing all anions or all cations.
  - New function for calculating dominant water types
    (dominant_water_type()) in a series of samples.
  - Tweak piper plots and stiff plots
      - Use Meas Alk (Total Alkalinity) instead of HCO3 if missing.
      - Omit outlier points (when >5 samples, those not in a Dominant
        Water Type)

                        Changes in version 0.6.0                        

  - Rename to bcgwcat to reflect change in scope
      - Update docs etc. in light of this
  - Added more details to Shiny app explaining private vs. public EMS
    data, water quality guidelines and parameter/unit changes
  - Fixed water quality summary to exclude Nitrate and Nitrate limits
    when measured as N (not applicable here)
  - Fixed bug, where piperplot did not respect EMS IDs to plot (ems_id
    argument)

                        Changes in version 0.5.1

                        Changes in version 0.5.0                        

  - piper_plot() can distinguish points by different groups.
    point_colour, point_filled, point_size and point_shape are now
    arguments which can specify group-level or overall styling of
    points.
  - piper_plot() has a new legend_position argument to move the legend,
    and legend_title argument to change the title
  - Data for piper plots is sorted before plotting to ensure correct
    legend order
  - New vignette for piper plots
  - dont_update works for interactive sessions as well
  - Prettier display in Shiny app when no data returned
  - Better handling of missing data by plotting functions

                        Changes in version 0.4.4                        

  - Add calculations for water type
  - Tweak piper plots data validity
  - Stiff plots only use valid data
  - Add minor elements
  - Charge balances can include missing values (rounded to 1 decimal)
  - Charge balances, anion sums and cation sums are recalculated
    completely
  - Update authors
  - Don't force users to update 2yr data in Shiny app

                        Changes in version 0.4.3

  - Added custom charge balance calculations (anion_sum2, cation_sum2,
    charge_balance2) and the option to choose between EMS charge
    balances and the one calculated here in the Shiny app

                        Changes in version 0.4.1
