Changes in version 0.4.7                        

  - changes the name of the primary function from xstatic_slurp to just
    xstatic
  - adds initial attempt at an interactive version, xstatic_interactive
    - to be completed
  - improves get_area_codes process. This now allows you (should allow
    you!) to pass in something like lad21 not just lad, if that is what
    your custom lookup requires
  - imported functions are all now namespaced to their package, so no
    more @importFrom decs
  - removes batch_size param from xstatic - it only ever needs to
    be 1000 anyway

                        Changes in version 0.4.4                        

  - Moves lookup to internal data as it should always have been (better
    understanding of data in packages nowadays thanks to Hadley)

                        Changes in version 0.4.3                        

  - Bit more tidying up and fixing things I just broke
  - Making the logic for parameter choice in get_dwp_codes more robust,
    and reworked it so default params are NULL, you can override with
    your own selections
  - changed period_id to measure_id but I am not sure if that is good or
    not
  - TODO: write up parameter choice combinations eg what to do if you
    want to switch from Universal Credit claims (caseload) dataset to
    the Households on UC dataset.

                        Changes in version 0.4.2                        

  - Not sure what happened to 0.4.1
  - Rejigged get_dwp_codes quite a bit. Some queries weren't working.
    Still needs better documentation.

                        Changes in version 0.4.0                        

  - Tidies up the chatty bits of get_dwp_codes

  - Restores the original name of the dwp_get_data_util function in
    dwp_get_data_util.R

  - Adds more comments to code

  - Fixes error in data-raw/get_lookup_data.R

  - Adds extra hack to get_dwp_codes.R to cover change of ds:
    
      if (ben %in% pension_type && ds == 3) {
      period = 2
      geo_type = 3
    }

    fixes issue #1 (!)

                        Changes in version 0.3.0                        

  - changes the name of the primary function from statx_slurp to
    xstatic_slurp!
  - (and changes the name of the relevant file)
  - makes significant changes to the parameter names of the main
    function:
      - location_level becomes filter_level
      - filter_location becomes filter_area
      - data_level becomes return_level
      - use_alias becomes use_aliases
      - and other standardisations between parameter names in the
        primary function and auxiliary functions
  - makes changes to the examples in the man page and in the README
  - adds additional explanation and makes corrections in README.md

                        Changes in version 0.2.0                        

  - many, many, many exhausting battles with the R package checks and
    documentation procedures
  - SO MANY mysterious and nonsensical error messages that contradict
    what's right in front of your eyes
  - ended up adding 'packagename::' to the beginning of most of my
    functions to get rid of warnings about packages not being found or
    properly available. I don't understand!
  - fixed the above by doing lots of @importFrom statements instead
  - but hopefully I have made this at last into a valid package... it's
    been a battle.
  - added Travis CI integration as per
    http://r-pkgs.had.co.nz/check.html#travis
  - added Code of Conduct statement
  - I learned that you don't need to source other R scripts in a
    package, just put them in the R folder and R will source them all
    automatically. source commands tend to cause devtools::check() to
    fail.

                        Changes in version 0.1.0                        

  - initial commit that works but maybe needs extending and maybe
    refactoring
  - wrote up README.md with acknowledgements and a commented example
