code: function tasks(server=false){
    let that = this;
    that.server = server;
    let tasks = determineTaskList(args.packages, server).filter(isRegisteredTask, that);
    return tasks;
  }
docs: the main function: creates a list of packages to operate on, using all registered packages unless the user provides a list. set server=true to use live_server_package list instead of all packages.
