Made a resolution to keep comments in the parsed data-structure
Added test-case (currently not working) similar to sample in README.md
Updated tests/metalanguage-synopsis.in to match current goal
Added parser (currently unused) for places where IP address group names may be interpolated in rule options
Break our child functions from being a 'where' clause to a top-level function, so they can be used in GHCi
Made individual rule option parsers top-level functions also
Resolved to improve whitespace handling in parser code
Hooked in the interpolated address groups into the -s and -d rule options
