    -- here for running the Pathman REST API
    
    Maintainer: Niklas Montin (niklas@cisco.com)
    20140710 - v1   basic command support, based on work by vrpolak@cisco.com
    20140716 - v2   SSL support and other http extras
    20140728 - v3   Adopted to Pathman
    20140824 - v4   Commandhandler2
    20141120 - v5   Removed need for Launcher - main section added
    20160413 - v6   Split out the actual handler to work with pathman and pathman_sr at the same time
