1. Create a base grade that contains all shared invokers and other parts for the processing of 3 endpoints;
2. the function gpii.qi.api.ci.results() might be refactored to use event listeners with priorities

component member options:
fluid.defaults("test", {
   regularOption1: "a"
   members: {
       memberOption1: "m",
   },
   events: {
       onProcess: null
   },
   listeners: {
       "onProcess.verifyURL": {
           priority: "first",
           ...
       },
       "onProcess.respond": {
           funcName: "readFile",
           priority: "after:verifyURL"
       }
   },
   // in case to override one listener:
   distributeOptions: {
       "distributeOnProcessRespond": {
           record: "makeGithubCall",
           target: "{that}.options.listeners.onProcess.respond"
       }
   }
});

that.output1 = output1; // output1 will live in members {}
