adding a page to the documentation for the setup of the IaaS server (not linked from within the docs)

changing the example landpoint files to be sorted lon,lat as the sort order gets enforced by the landpoint filter functions in postprocessing now.

adding a list of wildcards used when searching for nc file - useful if reporting that none are found

changing the optional SPATIAL_POINTS_FILE config parameter to SPATIAL_POINTS_FILE_TEMPLATE and allowing ${} value subsiitution in the paremeter value
removing some points from the ethiopia post processing landpoint file, to allow checking that the filtering for post-processing is working

It is possible to specify which spatial points file to use in the main config json. The default file will be used if not specified. This will allow us to perfrom historic runs with the old grid and specify manually.
The country-level points filtering used by the postprocessing steps (beofre plotting) now round down the acuracy when filtering points. This allows the country filtering to work with both the new and the old grid, as the differece is lost in the rounding

allowing the full iontegration pipeline for Surveys to use the standard deployment config, rather than trying to exclude WRSIS

making $PACKAGES_DIR a local variable and adding warnings about shared variable names at the pipeline level
