Changes in version 0.7.0                        

  - fix missing ddir in form_mapper()
  - clarify rule file usage and errors in facet_mapper()
  - Tweaks to align form_mapper flow decisions with the original
    LandMapR
  - Increase speed of QWETI calculations
  - Fix number of edge rows/cols removed
  - Add Topographical Summary outputs similar to those in Sheng et
    al. 2011 (summary_tables() etc. are now run by facet_mapper())
  - Fixed an discrepancy in wepp_mapper() which resulted in different
    channel mappings.
  - General tweaks and clean up of older usages

                        Changes in version 0.6.0                        

  - Import x/y coords or create them if they don't exist
  - flow_mapper() now requires grid or infers from x/y value of input
    files
      - form_mapper() and wepp_mapper() now use grid inferred from x/y
        value of flow_mapper() output files
  - flow_mapper() now has upslope_m (upslope cells * grid^2)
  - flow_mapper() calculates UCED
  - facet_mapper() calculates buffer edges
  - Simplify output with 'debug' argument (if false, removes
    intermediate files)
  - Simplify output columns by removing intermediate ones
  - Remove option to 'end' a run prematurely (required due to simplified
    output)
  - Remove dbf output option because it truncates column names
  - Fix flow_mapper() inconsistencies
  - Add extra data output "topographical_derivatives" in facet_mapper
  - Initial work on all_points data output

                        Changes in version 0.5.0                        

  - Load files forces to numeric (fixes problems where some imports in
    character)
  - Corrected slope_gc() directions (fixes #10)
  - Clarify output format and allow csv (fixes #13)
  - flow_mapper() has simplified output, similar to the other functions
    (fixes #12)
  - facet_mapper() has facets by number as well as by name, and ordered
    by crule (fixes #9)
  - form_mapper() values that are not on missing cells but can't be
    calculated due to local missingness, are assigned 0
  - Can load files even if dem in folder name (fixes #7)
  - Add rounding to match original LandMapR values where possible
  - Fix bug where grid parameter not passed on in form_mapper()

                        Changes in version 0.4.1                        

  - Added slope_gc() to calculate slope gradients and curvature (added
    to dem_fill through flow_mapper())
  - Added merge_flow_form() to create a single dem file from
    flow_mapper() dem_fill and all form_mapper() outputs.

                        Changes in version 0.4.0                        

  - Added facet_mapper() based on FacetMapR
  - Added wepp_mapper() based on WeppMapR
  - Internal changes to increase form_mapper() speed
  - Added ARULE deriving based on Li et al. 2011. Canadian Journal of
    Soil Science 91(2), 251-266.
  - Added both forms of calculating qweti, qarea, and lnqarea to
    form_mapper() (Originally values based on actual grid-cell area,
    now, qweti1, qarea1, lnqarea1 based on number of cells, and qweti2,
    qarea2, lnqarea2 based on grid-cell area).
  - Reduced number of output files
  - Updated reports

                        Changes in version 0.3.1                        

  - Update to tidyr v1.0.0

                        Changes in version 0.3.0                        

  - Added form_mapper() which mimics FormMapR
  - Renamed complete_run() to flow_mapper() to clarify what it refers to
  - Added new comparison reports
  - Fixed bugs related to incorrect vol2fl, parea and mm2fl
  - Added calculation of cumulative elevation differences to
    flow_mapper() which results in local_elev_diff (calculated after pit
    smoothing) and elev_diff (calculated after fill pits)

                        Changes in version 0.2.1                        

  - Minor bug fixes relating to fixing large flat pits

                        Changes in version 0.2.0                        

  - Major speed improvements, in some cases as much as 30x faster!
  - Added support for multiple input file types (?load_file for details)

                        Changes in version 0.1.0                        

  - Initial build of LITAP including functions to mimic FlowMapR
  - Runs include log and report of results
  - Added a NEWS.md file to track changes to the package.
