old2new_init.jq

#
# This little filter is for the 'jq' command line tool, and turns pre-refactor
# init_*.json files into the post-refactor style JSON.
#
# It's a work in progress, and only really deals with the AREMI specific data,
# but may be useful as a base for extension.
#
# To do the conversion, run something like the following command line:
#
# cat public/init_aremi.json | jq -f old2new_init.jq | grep -v '"legendUrl": null,' > output.json
#
