generate_html_proposals

#!/usr/bin/env python3
#
# Generate the html for a burgerforslag.
#
# Simple usage: The sole argument is the path to a burgerforslag-conforming json
# file.  Prints the html to standard output.
#
# Advanced usage: The first argument is '-b', the next N arguments are input
# json paths, and the final N arguments are output html paths.  Use this for
# batch processing.
