Node.js abstraction layer and automation framework.

    html =  f( "html", { get: "array", selector: "a" } ),

    split = f( "split" ),

    debug = f( "generic", (msg) => { console.log(msg.payload.attribs.href); } );

// Create flow
http.on("response", html);
html.on("success", split);

// Manually invoke flow
