Per @Greengroove's feedback, changing syntax to: [Show|Hide] # grp1 - grp2 - grp3 | mode mode can be any of these for the new Disable behavior: "Disable" "Comment" "Remove" (slightly different from FilterBlast impl) Any other mode is treated as the default behavior. Filtration always writes out as "Disable" or default (none) Also removed vestigal logging and comments.
